-	   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 or may not need RANLIB when building libraries.
+	    * calc*.i686.rpm

+		- all that is needed if you just want to use calc
-	   Comment the in/out the RANLIB value if ranlib does
-	   not work or does not exist.
 
-	   You may want to change the default pager used by calc.
+	    * calc-devel-*.i686.rpm
-	   As shipped the Makefile assumes 'more'.  On your system
+	        - calc *.h header and *.a lib files for use in other programs
-	   you may find 'less' to be a better pager.
 
-	   Set TOPDIR to be the place under which help files, calc,
+	    * calc.*.src.rpm
-	   include files and calc libs are to be installed.  As shipped
+	        - calc source in RPM package form
-	   the Makefile assumes a TOPDIR of /usr/local/lib.
 
-	   Set BINDIR to the place where calc is installed.  As shipped
+	The following 4 steps apply to calc source tree that comes from either:
-	   the Makefile assumes a BINDIR /usr/local/bin.
+
+		gunzip -c calc-*.tar.gz | tar -xvf -
+
+	or from:
+
+		rpm -ivh calc-*.src.rpm
+		cd /var/tmp
+		gunzip -c /usr/src/redhat/SOURCES/calc-*.tar.gz | tar -xvf -
+
+    1)	Look at the makefile, and adjust it to suit your needs.
+
+	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
+	    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.
+
+	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

+
+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,

+=-= 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*);
