+The following are the changes from calc version 2.11.6.0 to date:
+
+    Clarified remark in lucas.cal about use of n mod 2^n == 0.
+
+    Fixed help typos reported by Marc Mezzarobba <mm at mm dot ovh dot org>.
+
+    Forced system("") to return 0 under windoz.
+
+    The direct.h include file is not used when compiling under Cygwin.
+
+    Fixed bug where random(10,11) caused calc to dump core when issued
+    the 2nd time.
+
+    Moved the setting of the Makefile variable ${CALC_INCDIR} to
+    the section where things like ${BINDIR} and ${LIBDIR} are set.

+
+    The Makefile is shipped mode 0644 since a number of folks
+    edit it (to build and check calc) as a non-root user and later
+    on su to root to install.  Idea from Clifford Kite <kite_public1
+    at ev1 dot net>.
+
+    Added base2() builtin function to calc.  Normally calc prints
+    values according to base().  Frequently some users want to see
+    a value in two bases.  Flipping back and forth between to bases
+    is a bit of a pain.  With base2(), calc will output a value twice:
+
+	; 234567
+		234567
+	; base2(16),
+	; 234567
+		234567 /* 0x39447 */
+	; 131072
+		131072 /* 0x20000 */
+	; base2(0),
+	; 131072
+        131072
+
+    By default, base2() is disabled.  Calling base2(0) will also turn
+    off the double base mode.  Thanks goes to Erik Anggard
+    <eriki dot anggardi at packetfronti dot com> for his idea and
+    his initial patch.

 Installing calc in 4 easy steps:
 
-    1) Look at the makefile, and adjust it to suit your needs.
+    1)	Look at the makefile, and adjust it to suit your needs.
 
-       Here are some Makefile hints:
+	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.
 
-	   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.
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+	! If you are building under Windoz or a Windoz-like environment !
+	! (such as Cygwin or DJGPP), read the README.WINDOWS file.      !
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 
-	   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.
+	You should determine if these Makefile variables are reasonable:
 
-	   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.
+	    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.
 
-	   Set BINDIR to the directory where calc is installed.
-	   As shipped the Makefile assumes BINDIR is /usr/local/bin.
+	You may want to change the default installation locations for
+	these values, which are based on the 4 values listed above:
 
-	   Set SHAREDIR to the place where shared files are kept.
-	   As shipped the Makefile assumes that SHAREDIR is /usr/share.
-	   Calc places its shared files under ${SHAREDIR}/calc.
+	    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
 
-	   Set INCDIR to the place where .h header files are kept.
-	   As shipped the Makefile assumes that INCDIR is /usr/include.
-	   Calc places its .h header files under ${INCDIR}/calc.
+	If you want to install calc files under a top level directory,
+	then set the T value:
 
-	   Set LIBDIR to be the place under which help files, calc,
-	   include files and calc libs are to be installed.
-	   As shipped the Makefile assumes a LIBDIR of /usr/lib.
-	   The calc library is installed as ${LIBDIR}/libcalc.a.
+	    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.
 
-	   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.
+	    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

+SYNOPSIS

+
+TYPES
+    mode	real
+
+    return	real
+
+DESCRIPTION
+    By default, calc will output values according to the default base
+    as controlled by the base() builtin function.
+
+    The base2() builtin function, if given a non-zero argument, enables
+    double base output mode.  In double base output mode, calc values
+    are displayed twice, once according to base() and again according
+    to base2().  In double base output mode, the second time a value is
+    displayed, it is displayed within comments:
+
+	21701 /* 0x54c5 */
+
+    The arguments for base2() are identical to base() with the addition
+    of the 0 value:
+
+	     base2	equivalent
+		      config("mode2")'s
+
+	       2	"binary"	base 2 fractions
+			"bin"
+
+	       8	"octal"		base 8 fractions
+			"oct"
+
+	      10	"real"		base 10 floating point
+			"float"
+			"default"
+
+	     -10	"integer"	base 10 integers
+			"int"
+
+	      16	"hexadecimal"	base 16 fractions
+			"hex"
+
+	     1/3	"fraction"	base 10 fractions
+			"frac"
+
+	    1e20	"scientific"	base 10 scientific notation
+			"sci"
+			"exp"
+
+	       0	"off"		disable double base output
+
+    For convenience, any non-integer non-zero value is assumed to mean
+    base 10 fractions and any integer >= 2^64 is assumed to mean base 10
+    scientific notation.
+
+    These base2() calls have the same meaning as config("mode2", "fraction"):
+
+	base2(1/3)	base2(0.1415)	base2(16/37)
+
+    These base2() calls have the same meaning as config("mode2", "scientific"):
+
+	base2(1e20)	base2(2^64)	base2(2^8191-1)
+
+    However the base2() function will only return one of the base values
+    listed in the table above.
