     * There is a bug in gcc-2.95 that causes calc, when compiled with -O2,

       or to use gcc-2.96 or later.

-
-	    #include <stdio.h>
-	    #define SVAL(a,b) (unsigned long)(0x ## a ## b ## ULL)
-	    main(){SVAL(b8a8aeb0,8168eadc);}
-
-      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.

+	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
+	    CUSTOMINCPDIR      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.

+Dear calc user on a Windoz based system,
+
+See the HOWTO.INSTALL file for information on how to build and install calc.
+See also the README file.
+
+NOTE: The main developers do not have access to a Windoz based platform.
+      While we will make an effort to not break calc Windoz based system,
+      our lack of a Windoz test environment will mean we will make mistakes
+      from time to time.  Hopefully Windowz users can overcome these mistakes.
+      Of course you are welcome to send us any patches that fix your
+      Windoz build environment.

+=-= compiling under DJGPP =-=
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+You might want to try using the DJGPP system to compile calc.  See:
+
+	http://www.delorie.com/djgpp/
+
+for DJGPP details and availability.
+
+To compile with DJGPP, one needs to select a number of Makefile
+variable changes.  Eli Zaretskii <eliz at is dot elta dot co dot il>
+recommends the following settings:
+
+	TERMCONTROL= -DUSE_TERMIOS
+	BYTE_ORDER= -DLITTLE_ENDIAN
+	LONG_BITS= 32
+	HAVE_FPOS_POS= -DHAVE_NO_FPOS_POS
+	FPOS_BITS= 32
+	OFF_T_BITS= 32
+	DEV_BITS= 32
+	INODE_BITS= 32
+	HAVE_USTAT= -DHAVE_NO_USTAT
+	HAVE_GETSID= -DHAVE_NO_GETSID
+	HAVE_GETPGID= -DHAVE_NO_GETPGID
+	HAVE_GETTIME= -DHAVE_NO_GETTIME
+	HAVE_GETPRID= -DHAVE_NO_GETPRID
+	HAVE_URANDOM_H= NO
+	ALIGN32= -UMUST_ALIGN32
+	HAVE_MALLOC_H= YES
+	HAVE_STDLIB_H= YES
+	HAVE_STRING_H= YES
+	HAVE_TIMES_H= NO
+	HAVE_SYS_TIMES_H= YES
+	HAVE_TIME_H= YES
+	HAVE_SYS_TIME_H= YES
+	HAVE_UNISTD_H= YES
+	BINDIR= /dev/env/DJDIR/bin
+	INCDIR= /dev/env/DJDIR/include
+	LIBDIR= /dev/env/DJDIR/lib
+	MANDIR= /dev/env/DJDIR/man/man1
+	CATDIR= /dev/env/DJDIR/man/cat1
+	NROFF= groff
+	CALCPATH= .;./cal;~/.cal;${CALC_SHAREDIR};${CUSTOMCALDIR}
+	CALCRC= ${CALC_SHAREDIR}/startup;~/.calcrc;./.calcinit
+	CALCPAGER= less.exe -ci
+	DEBUG= -O2 -gstabs+
+
+The 'Linux set' or 'gcc set' (see the Select your compiler type section)
+should work for DJGPP systems if you set the above Makefile variables.
+
+Look for Makefile comments of the form:
+
+	# Select ...something... for DJGPP.
+
+Follow those recommendations.  In cases where they conflict with
+the above Makefile list, follow the recommendation in the Makefile.

+=-= compiling with Cygwin =-=
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+An effort is being made to allow windows users to compile calc using the
+Cygwin project (http://sources.redhat.com/cygwin/) with the GCC compiler
+and Un*x tools for Windows.
+
+The major porting work was performed by Thomas Jones-Low
+(tjoneslo at softstart dot com).  He said:
+
+    I had previous stated to this group that I have successfully managed
+    to port a version of Calc to Windows, and promised some point to
+    post what was required, so here it is.
+
+    One obvious manner of doing this port is to get the latest version
+    of the Cygwin project (http://sources.redhat.com/cygwin/) with the
+    GCC compiler and Un*x tools for Windows and recompile.
+
+    I built my working version using Calc ... I am using Visual C++
+    version 7.0, which is an older version of the Microsoft development
+    tools. The make file provided with Calc is not compatible with
+    NMAKE, so I used the Visual Studio tools to generate another one
+    (not included). Calc is built in two parts, calc.dll, which is the
+    library, and calc.exe which is the command line interface.
+
+He recommended that you generate by hand all of the header files that
+by the Makefile.  This has been done for you via the makefile rule:
+
+	make win32_hsrc
+
+which uses the Makefile variables in win32.mkdef to form these header
+files under win32 directory.
+
+You will find generated versions of these files located in the win32
+sub-directory.  These files may be appropriate for your Cygwin building
+needs.
+
+In particular:
+
+	Just copy the win32/*.[ch] files up into the top level calc
+	source directory, edit them (if needed) and build using the
+	Cygwin GCC compiler and Cygwin build environment.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+=-=-= calc maintenance folk =-=-=
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+People who maintain calc need to keep in mind the following:
+
+The following was added to opcodes.h, config.h, zmath.h and value.h:
+
+	#if defined(_WIN32)
+	#ifdef _EXPORTING
+	  #define DLL	__declspec(dllexport)
+	#else
+	  #define DLL	__declspec(dllimport)
+	#endif
+
+	#else /* Windoz free systems */
+
+	  #define DLL
+
+	#endif /* Windoz free systems */
+
+Then DLL was added in front of all the exported functions.  For example:
+
+    extern int configtype(char*);
+
+was changed to:
+
+    DLL extern int configtype(char*);

 The following is a brief description of some of the calc resource files
 that are shipped with calc.  See above for example of how to read in
 and execute these files.
 
+alg_config.cal
+
+    global test_time
+    mul_loop(repeat,x) defined
+    mul_ratio(len) defined
+    best_mul2() defined
+    sq_loop(repeat,x) defined
+    sq_ratio(len) 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.
