-    * There is a bug in some versions of the Dec/Compaq cc for the Alpha

-	    main(){SVAL(b8a8aeb0,8168eadc);}
+	if (expr)
+	{
+	    ...
+	}
 
-      fails because it puts a space inside the concatenated hex.  Calc
-      has code that is affected by this bug.  This bug has been reported
-      to Compaq and may be fixed in the future.	 A work-a-round is to
-      compile with cc -std0 or to use a later version of their compiler.
-
-    * On a Digital UNIX V4.0F (Rev. 1229) on a 500 Mhz 21264, make check
-      dies a horrible death starting in test 600 and 622 gives 100s of
-      messages for calc version 2.11.0t9.4 using the Dec's cc with -O2:

-	it finally hangs at test 2000.
-
-      The work-a-round is to compile calc without the optimizer.  If this
-      happens to you, try compiling without -O and without -O2.	 I.e., in
-      the Makefile, set:
-
-	DEBUG= -g

-      support in gcc-2.96 is very unofficial and thus there is no
-      work-a-round for gcc-2-96.
-
-      There is a work-a-round for this architecture us one is using the
-      Solaris CC on the sparcv9.  It has been reported that setting the
-      following Makefile variables will produce a working version of
-      calc on the sparcv9 under 64 bit Solaris:
-
-	    LCC="cc -xarch=v9"
-	    CCWARN="-DFORCE_STDC -w"
-	    DEBUG="-fast -xarch=v9"

-	/usr/include/ctype.h:161: warning: `__isctype' defined but not used
-	/usr/include/ctype.h:170: warning: `toupper' defined but not used
-	/usr/include/ctype.h:177: warning: `tolower' defined but not used
-
-      are seen.	 These warnings are the result of mis-features in BSDI
-      include files.  They do not have an impact on the operation
-      or performance.  The work-a-round is to ignore these warnings
-      under BSDI.
+      This needs to be changed.  See also "help statement", "help unexpected",
+      and "help todo".

-Installing calc in 4 easy steps:
+Installing calc from the bzip2-ed tarball in 4 easy steps:
 
-    1) Look at the makefile, and adjust it to suit your needs.
+    0)  If your platform supports i686 RPMs, you may want to go to:
 
-       Here are some Makefile hints:
+	    http://www.isthe.com/chongo/src/calc/
 
-	   Select a compiler set by commenting in the appropriate set
-	   of cc options.  As shipped the Makefile assumes a gcc-like
-	   environment such as Linux.  If a more appropriate cc set if
-	   found below, comment out the Linux set and comment in that
-	   set or edit the gcc set or the common cc set as needed.
+	and use these RPMs:
 
-	   You may or may not need RANLIB when building libraries.
-	   As shipped the Makefile assumes RANLIB is needed.
-	   Comment the in/out the RANLIB value if ranlib does
-	   not work or does not exist.
+	    * calc*.i686.rpm
+		- all that is needed if you just want to use calc
 
-	   You may want to change the default pager used by calc.
-	   As shipped the Makefile assumes 'more'.  On your system
-	   you may find 'less' to be a better pager.
+	    * calc-devel-*.i686.rpm
+	        - calc *.h header and *.a lib files for use in other programs
 
-	   Set TOPDIR to be the place under which help files, calc,
-	   include files and calc libs are to be installed.  As shipped
-	   the Makefile assumes a TOPDIR of /usr/local/lib.
+	    * calc.*.src.rpm
+	        - calc source in RPM package form
 
-	   Set BINDIR to the place where calc is installed.  As shipped
-	   the Makefile assumes a BINDIR /usr/local/bin.
+	The following 4 steps apply to calc source tree that comes from either:
+
+		bunzip2 -c calc-*.tar.bz2 | tar -xvf -
+
+	or from:
+
+		rpm -ivh calc-*.src.rpm
+		cd /var/tmp
+		bunzip2 -c /usr/src/redhat/SOURCES/calc-*.tar.bz2 | tar -xvf -
+
+    1)	Look at the makefile, and adjust it to suit your needs.
+
+	The top level Makefile and the custom/Makefile require a GNU
+	Make (such as gmake) or an equivalently advanced make.	On many
+	targets, the default make is sufficent.  On FreeBSD for example,
+	one must use gmake instead of make.
+
+	If your target system does not have GNU Make (or equivalent), then
+	you should try using the Makefile.simple and custom/Makefile.simple
+	files:
+
+	    mv Makefile Makefile.gmake
+	    cp Makefile.simple Makefile
+	    mv custom/Makefile custom/Makefile.gmake
+	    cp custom/Makefile.simple custom/Makefile
+
+	The Makefile, as shipped, is suitable for installation under
+	Linux and Un*x-like environments.  For the most part, the default
+	values should work.  If in doubt, follow the 'When in doubt'
+	suggestion.
+
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+	! If you are building under Windoz or a Windoz-like environment !
+	! (such as Cygwin or DJGPP), read the README.WINDOWS file.      !
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+
+	You should determine if these Makefile variables are reasonable:
+
+	    INCDIR		Where the system include (.h) files are kept.
+	    BINDIR		Where to install calc binary files.
+	    LIBDIR		Where to install calc link library (*.a) files.
+	    CALC_SHAREDIR	Where to install calc help, .cal, startup, and
+	    			config files.
+
+	You may want to change the default installation locations for
+	these values, which are based on the 4 values listed above:
+
+	    HELPDIR            where the help directory is installed
+	    CALC_INCDIR        where the calc include files are installed
+	    CUSTOMCALDIR       where custom *.cal files are installed
+	    CUSTOMHELPDIR      where custom help files are installed
+	    CUSTOMINCDIR       where custom .h files are installed
+	    SCRIPTDIR          where calc shell scripts are installed
+
+	If you want to install calc files under a top level directory,
+	then set the T value:
+
+	    The calc install is performed under ${T}, the calc build is
+	    performed under /.	The purpose for ${T} is to allow someone
+	    to install calc somewhere other than into the system area.
+
+	    For example, if:
+
+	    	BINDIR= /usr/bin
+		LIBDIR= /usr/lib
+		CALC_SHAREDIR= /usr/share/calc
+
+	    and if:
+
+	    	T= /var/tmp/testing
+
+	    Then the installation locations will be:
+
+		calc binary files:	/var/tmp/testing/usr/bin
+		calc link library:	/var/tmp/testing/usr/lib
+		calc help, .cal ...:	/var/tmp/testing/usr/share/calc
+		... etc ...		/var/tmp/testing/...
+
+	    If ${T} is empty, calc is installed under /, which is the same
+	    top of tree for which it was built.  If ${T} is non-empty, then
+	    calc is installed under ${T}, as if one had to chroot under
+	    ${T} for calc to operate.
+
+	Look for the section that starts:
+
+	    ################
+	    # compiler set #
+	    ################
+
+	    Select a compiler set by commenting in the appropriate set
+	    of cc options.  As shipped the Makefile assumes a gcc-like
+	    environment such as Linux.  If a more appropriate cc set if
+	    found below, comment out the Linux set and comment in that
+	    set or edit the gcc set or the common cc set as needed.
+
+	You may want to change these Makrfile variables from their defaults:
+
+	    RANLIB
+
+		You may or may not need RANLIB when building libraries.
+		As shipped the Makefile assumes RANLIB is needed.
+		Comment the in/out the RANLIB value if ranlib does
+		not work or does not exist.
+
+	    CALCPAGER
+
+		You may want to change the default pager used by calc.
+		As shipped the Makefile assumes 'more'.  On your system
+		you may find 'less' to be a better pager.
+
+	    DEBUG
+
+	       Some compilers (to put it mildly) have bugs.  Sometimes the
+	       DEBUG Makefile variable causes the compiler / optimizer to
+	       produce bad code.  Other compilers do just fine.
+
+	       If possible try to use DEBUG=-O3 -g3 (maximum optimization
+	       and debug symbols).  If the calc test fails (see step 3),
+	       try lowering either the -O value and/or the -g3.  Also try
+	       using -Osomething without -g.
 
 	   Adjust other Makefile variables as needed.

-format string and optional arguments.  (However, none of the low level math
-routines currently uses formatting, so if you are lazy you can simply use
-the first argument as a simple error string.)  For example, one of the
-error calls you might expect to receive is:
+The math_error() function is called by the math routines on an error
+condition, such as malloc failures, division by zero, or some form of
+an internal computation error.  The routine is called in the manner of
+printf, with a format string and optional arguments:
 
-	math_error("Division by zero");
+	    void math_error(char *fmt, ...);
 
-Your program can handle errors in basically one of two ways.  Firstly, it
-can simply print the error message and then exit.  Secondly, you can make
-use of setjmp and longjmp in your program.  Use setjmp at some appropriate
-level in your program, and use longjmp in the math_error routine to return
-to that level and so recover from the error.  This is what the calc program
-does.
+Your program must handle math errors in one of three ways:
 
-For convenience, the link library libcalc.a contains a math_error routine.
-By default, this routine simply prints a message to stderr and then exits.
-By simply linking in this link library, any calc errors will result in a
-error message on stderr followed by an exit.
+    1) Print the error message and then exit
 
-External programs that wish to use this math_error may want to compile with:
+	There is a math_error() function supplied with the calc library.
+	By default, this routine simply prints a message to stderr and
+	then exits.  By simply linking in this link library, any calc
+	errors will result in a error message on stderr followed by
+	an exit.
 
-	-I${LIBDIR} -L${LIBDIR} -lcalc
+    2) Use setjmp and longjmp in your program
 
-If one sets up calc_jmp_buf, and then sets calc_jmp to non-zero then
-this routine will longjmp back (with the value of calc_jmp) instead.
-In addition, the last calc error message will be found in calc_error;
-this error is not printed to stderr.  The calc error message will
-not have a trailing newline.
+	Use setjmp at some appropriate level in your program, and let
+	the longjmp in math_error() return to that level and to allow you
+	to recover from the error.  This is what the calc program does.
 
-For example:
+	If one sets up calc_matherr_jmpbuf, and then sets
+	calc_use_matherr_jmpbuf to non-zero then math_error() will
+	longjmp back with the return value of calc_use_matherr_jmpbuf.
+	In addition, the last calc error message will be found in
+	calc_err_msg; this error is not printed to stderr.  The calc
+	error message will not have a trailing newline.
 
-    #include <setjmp.h>
+	For example:
 
-    extern jmp_buf calc_jmp_buf;
-    extern int calc_jmp;
-    extern char *calc_error;
-    int error;
+	    #include <setjmp.h>
+	    #include "lib_calc.h"
 
-    ...
+	    int error;
 
-    if ((error = setjmp(calc_jmp_buf)) != 0) {
+	    ...
 
-	    /* reinitialize calc after a longjmp */
-	    reinitialize();
+	    if ((error = setjmp(calc_matherr_jmpbuf)) != 0) {
+
+		    /* report the error */
+		    printf("Ouch: %s\n", calc_err_msg);
+
+		    /* reinitialize calc after the longjmp */
+		    reinitialize();
+	    }
+	    calc_use_matherr_jmpbuf = 1;
+
+	If calc_use_matherr_jmpbuf is non-zero, then the jmp_buf value
+	calc_matherr_jmpbuf must be initialized by the setjmp() function
+	or your program will crash.
+
+    3) Supply your own math_error function:
+
+	    void math_error(char *fmt, ...);
+
+	Your math_error() function may exit or transfer control to outside
+	of the calc library, but it must never return or calc will crash.
+
+External programs can obtain the appropriate calc symbols by compiling with:
+
+	-I${INCDIR} -L${LIBDIR} -lcalc
+
+-------------------------
+PARSE/SCAN ERROR HANDLING
+-------------------------
+
+The scanerror() function is called when calc encounters a parse/scan
+error.  For example, scanerror() is called when calc is given code
+with a syntax error.
+
+The variable, calc_print_scanerr_msg, controls if calc prints to stderr,
+any parse/scan errors.  By default, this variable it set to 1 and so
+parse/scan errors are printed to stderr.  By setting this value to zero,
+parse/scan errors are not printed:
+
+	#include "lib_calc.h"
+
+	/* do not print parse/scan errors to stderr */
+	calc_print_scanerr_msg = 0;
+
+The last calc math error or calc parse/scan error message is kept
+in the NUL terminated buffer:
+
+	char calc_err_msg[MAXERROR+1];
+
+The value of calc_print_scanerr_msg does not change the use
+of the calc_err_msg[] buffer.  Messages are stored in that
+buffer regardless of the calc_print_scanerr_msg value.
+
+The calc_print_scanerr_msg and the calc_err_msg[] buffer are declared
+lib_calc.h include file.  The initialized storage for these variables
+comes from the calc library.  The MAXERROR symbol is also declared in
+the lib_calc.h include file.
+
+Your program must handle parse/scan errors in one of two ways:
+
+    1) exit on error
+
+	If you do not setup the calc_scanerr_jmpbuf, then when calc
+	encounters a parse/scan error, a message will be printed to
+	stderr and calc will exit.
+
+    2) Use setjmp and longjmp in your program
+
+	Use setjmp at some appropriate level in your program, and let
+	the longjmp in scanerror() return to that level and to allow you
+	to recover from the error.  This is what the calc program does.
+
+	If one sets up calc_scanerr_jmpbuf, and then sets
+	calc_use_scanerr_jmpbuf to non-zero then scanerror() will longjmp
+	back with the return with a non-zero code.  In addition, the last
+	calc error message will be found in calc_err_msg[]; this error is
+	not printed to stderr.	The calc error message will not have a
+	trailing newline.
+
+	For example:
+
+	    #include <setjmp.h>
+	    #include "lib_calc.h"
+
+	    int scan_error;
+
+	    ...
+
+	    /* delay the printing of the parse/scan error */
+	    calc_use_scanerr_jmpbuf = 0;	/* this is optional */
+
+	    if ((scan_error = setjmp(calc_scanerr_jmpbuf)) != 0) {
+
+		    /* report the parse/scan */
+		    if (calc_use_scanerr_jmpbuf == 0) {
+			    printf("parse error: %s\n", calc_err_msg);
+	    	    }
+
+		    /* initialize calc after the longjmp */
+		    initialize();
+	    }
+	    calc_use_scanerr_jmpbuf = 1;
+
+	If calc_use_scanerr_jmpbuf is non-zero, then the jmp_buf value
+	calc_scanerr_jmpbuf must be initialized by the setjmp() function
+	or your program will crash.
+
+External programs can obtain the appropriate calc symbols by compiling with:
+
+	-I${INCDIR} -L${LIBDIR} -lcalc
+
+---------------------------
+PARSE/SCAN WARNING HANDLING
+---------------------------
+
+Calc parse/scan warning message are printed to stderr by the warning()
+function.  The routine is called in the manner of printf, with a format
+string and optional arguments:
+
+	void warning(char *fmt, ...);
+
+The variable, calc_print_scanwarn_msg, controls if calc prints to stderr,
+any parse/scan warnings.  By default, this variable it set to 1 and so
+parse/scan warnings are printed to stderr.  By setting this value to zero,
+parse/scan warnings are not printed:
+
+	#include "lib_calc.h"
+
+	/* do not print parse/scan warnings to stderr */
+	calc_print_scanwarn_msg = 0;
+
+The last calc calc parse/scan warning message is kept in the NUL
+terminated buffer:
+
+	char calc_warn_msg[MAXERROR+1];
+
+The value of calc_print_scanwarn_msg does not change the use
+of the calc_warn_msg[] buffer.  Messages are stored in that
+buffer regardless of the calc_print_scanwarn_msg value.
+
+Your program must handle parse/scan warnings in one of two ways:
+
+    1) print the warning to stderr and continue
+
+	The warning() from libcalc prints warning messages to
+	stderr and returns.  The flow of execution is not changed.
+	This is what calc does by default.
+
+    2) Supply your own warning function:
+
+	    void warning(char *fmt, ...);
+
+	Your warning function should simply return when it is finished.
+
+External programs can obtain the appropriate calc symbols by compiling with:
+
+	-I${INCDIR} -L${LIBDIR} -lcalc
 
-	    /* report the error */
-	    printf("Ouch: %s\n", calc_error);
-    }
-    calc_jmp = 1;

 that are shipped with calc.  See above for example of how to read in
 and execute these files.

+    mul_loop(repeat,x) defined
+    mul_ratio(len) defined
+    best_mul2() defined
+    sq_loop(repeat,x) defined

+    best_sq2() defined
+    pow_loop(repeat,x,ex) defined
+    pow_ratio(len) defined
+    best_pow2() defined
+
+    These functions search for an optimal value of config("mul2"),
+    config("sq2"), and config("pow2").  The calc default values of these
+    configuration values were set by running this resource file on a
+    1.8GHz AMD 32-bit CPU of ~3406 BogoMIPS.
+
+    The best_mul2() function returns the optimal value of config("mul2").
+    The best_sq2() function returns the optimal value of config("sq2").
+    The best_pow2() function returns the optimal value of config("pow2").
+    The other functions are just support functions.
+
+    By design, best_mul2(), best_sq2(), and best_pow2() take a few
+    minutes to run.  These functions increase the number of times a
+    given computational loop is executed until a minimum amount of CPU
+    time is consumed.  To watch these functions progress, one can set
+    the config("user_debug") value.
+
+    Here is a suggested way to use this resource file:
+
+	; read alg_config
+	; config("user_debug",2),;
+	; best_mul2(); best_sq2(); best_pow2();
+	; best_mul2(); best_sq2(); best_pow2();
+	; best_mul2(); best_sq2(); best_pow2();
+
+    NOTE: It is perfectly normal for the optimal value returned to differ
+    slightly from run to run.  Slight variations due to inaccuracy in
+    CPU timings will cause the best value returned to differ slightly
+    from run to run.
+
+    One can use a calc startup file to change the initial values of
+    config("mul2"), config("sq2"), and config("pow2").  For example one
+    can place into ~/.calcrc these lines:
+
+	config("mul2", 1780),;
+	config("sq2", 3388),;
+	config("pow2", 176),;
+
+    to automatically and silently change these config values.
+    See help/config and CALCRC in help/environment for more information.

-%description
-Calc is an interactive calculator which provides for easy large numeric
-calculations, but which also can be easily programmed for difficult or
-long calculations.
-
-All numbers are represented as fractions with arbitrarily large numerators
-and denominators which are always reduced to lowest terms.  Real or
-exponential format numbers are converted to the equivalent fraction.
-One use enter decinal, hex, octal, binary and complex values.
-
-Commands are statements in a C-like language, where each input line is
-treated as the body of a procedure.  You can define your own functions
-by using the 'define' keyword, followed by a function declaration very
-similar to C.  Calc also comes with a rich set of builtin functions
-and calc shell commands.
-
-In addition to numeric global, local and static variables, Calc as
-lists, associated arrays, matrices, byte blocks, dymanic strings and
-user defined objects.
