+The following are the changes from calc version 2.12.4.3 to date:
+
+    Added gvec.cal resource script.
+
+    Added calc-symlink make rulle to setup symlinks from stardard locations
+    into a tree specified by a non-empty ${T} makefile variable.  Added
+    calc-unsymlink to remove any symlinks that may have been created by
+    the calc-symlink rule.
+
+
+The following are the changes from calc version 2.12.4.0 to 2.12.4.2:
+
+    Fixed a documentation bug for the sgn() builtin.
+
+    Added the 1<<8/2 evaluation example to "help unexpected".  That
+    expression evalutes to 128, not 16 as some C programmers might expect.
+
+    Fixed a bug in solve.cal where high was not returned in some situations.
+
+    Fixed a bug reported by Paul & Karen Tomlinson (paulnkaz at pktomlinson
+    dot fsnet dot co dot uk) where calling log multiple times with different
+    values of epsilon resulted in an incorrect value.
+
+    Removed cvd rule from Makefiles.
+
+    The Makefile used in the source rpm (calc-*.src.rpm) no longer uses
+    the -Werror compile flag.  This is to help those distributions with
+    compilers that make produce (hopefully) complination warnings.
+    NOTE: For testing and calc build purposes will recommend and will
+    continue to use the -Werror flag.
+
+    Fixed a typo in the Makefile where the make variable ${SAMPLE_OBJ}
+    was misspelled as ${SAMPLE_OBJS}.
+
+    Added prep makefile rule to make is easier to compile calc without
+    an optimizer.  By doing:
+
+    	make clobber prep
+
+    one may build a calc binary that is easier to debug.
+
+    Fixed a bug where an certains typos (e.g., calling an unknown
+    function) would previously cause calc to exit.
+
+    Updated the COPYING file to reflect the new filenames associated
+    with the SHA1 hash function, and removed mention of files related
+    to the SHA (SHA0, not SHA1) and the MD5 hash functions (which is
+    no longer supported in calc).
+
+    Fixed a bug where a calling vsnprintf() twice created problems.
+    The thanks for this fix goes to Matthew Miller (mattdm at mattdm
+    dot org) for this patch.
+
+    Michael Penk (mpenk at wuska dot com) reported success in installs
+    under windoz via Cygwin by making a change to the Cygwin target.
+    These changes have been folded into the main calc Makefile.
+    The old recommendation of using 'make win32_hsrc' is no longer
+    required for Cygwin.  See the README.WINDOWS file for details.
+
+    Added dms.cal and hms.cal resource files.  The dms.cal is a more
+    functional version of deg.cal.  It is a superset except that increment
+    and decrement is on the arc second level.  The hms.cal is for
+    24-hour cycle instread of the 360 degree cycle of dms.cal.
+
+    Changed deg.cal object name from dms to deg so that the more functional
+    dms.cal can own the dms object name.
+
+    Updated 'help obj' to reflect changes to 'show objfunctions' and
+    resource file example list since 1999.
+
+    Fixed problem where CALC_BYTE_ORDER refering to CALC_BIG_ENDIAN
+    and CALC_LITTLE_ENDIAN instead of BIG_ENDIAN and LITTLE_ENDIAN.
+
+
+The following are the changes from calc version 2.12.3.0 to 2.12.3.3:
+
+    Fixed the Jacobi function where it returned 1 when it should have
+    returned 0.  Thanks goes to Kevin Sopp (baraclese at googlemail dot com)
+    for discovering the problem and suggesting the nature if the fix.
+
+    Calc versions will always be of the form x.y.z.w even when the
+    MINOR_PATCH (w) is 0.  Thus, 2.12.3.0 will be printed as 2.12.3.0
+    instread of just 2.12.3.
+
+    Added MINGW32_NT-5.0 compile target based on a patch from
+    Brian L. Angus (angus at eng dot utah dot edu).
+
+    Removed the use of rpm.release in the Makefile.
+
+    Mac OS Darwin targets no longer attempt to use ldconfig.  Under the
+    Darwin target, the LDCONFIG make variable is redefined to be
+    an empty value.  Thanks goes to Ralf Trinler (art at infra dot de)
+    for reporting this problem.
+
+    The ${CALC_INCDIR}/custom is no longer being removed at install time
+    if it is empty.  Now when ${ALLOW_CUSTOM} make variable is empty,
+    an empty ${CALC_INCDIR}/custom may be left hehind.
+
+    Fixed a problem where a "make clobber" would remove custom/Makefile
+    and fail to rebuilt it.
+
+
+The following are the changes from calc version 2.12.2.3 to 2.12.2.4:
+
+    Added OpenBSD target.
+
+    Using the -r test instead of the -e test in Makefiles because some
+    out of date shells still do not have the -e test.
+
+    The Makefile now avoids the use of if ! command because some out of
+    date shells to not support the ! construct.

    purposes.  By default, the calc rpm installed stripped binaries
    and libraries.

+    Added this high priority item to the calc help/todo list:
+
+	It is overkill to have nearly everything wind up in libcalc.
+	Form a libcalcmath and a libcalclang so that an application
+	that just wants to link with the calc math libs can use them
+	without dragging in all of the other calc language, I/O,
+	and builtin functions.
+
+    Fixed the wording for the -i flag in the calc man page.
+
+    Added some notes to the help/unexpected file regarding calc
+    and interactice shells.
+
+    Fixed bug where a FILEPOS was copied FPOS_POS_BITS octets instead of
+    FPOS_POS_LEN octets.
+
+    Split out ${READLINE_EXTRAS} Makefile variables from ${READLINE_LIB}
+    to better deal with Fedora rpm requirements.
+
+    Bit 8 (0x80) of calc_debug is reserved for custom debugging.
+    See help/config and custom/HOW_TO_ADD for details.
+
+    When the Makefile variable ${ALLOW_CUSTOM} is not defined or empty,
+    the libcustcalc library is not built or linked against, certain make
+    rules skip going into the custom sub-directory, the install
+    rule skips certain custom installation actions, and the common
+    C flags (${COMMON_CFLAGS}) is given -UCUSTOM.  Other make rules such
+    as "make clean" and "make clobber" still work as before.  Also
+    the Makefile.simple assumes that the Makefile variable ${ALLOW_CUSTOM}
+    is -DCUSTOM.
+
+    Clarified that the calc builtin functions rand() and random()
+    operate over a half closed interval.  The help/rand and help/random
+    refer to  the top of the interval as "beyond" instead of "max".
+
+    Releaseing source tar balls using bzip2 instead of with gzip.  So
+    what was calc-something.tar.gz is now calc-something.tar.bz2.
+    To "uncompress" use:
+
+    	bunzip2 calc-something.tar.bz2
+
+    On some systems, one may untar directly by:
+
+	tar -jxvf calc-something.tar.bz2
+
+   The Makefile variable ${BYTE_ORDER} was replaced by ${CALC_BYTE_ORDER}.
+
+   Changed the way the Makefile can force the calc byte order.  If you set
+   the Makefile variable ${CALC_BYTE_ORDER} to be -DCALC_BIG_ENDIAN then
+   endian.h will force the CPP symbol CALC_BYTE_ORDER to be BIG_ENDIAN.
+   If you set ${CALC_BYTE_ORDER} to be -DCALC_LITTLE_ENDIAN then endian.h
+   will force the CPP symbol CALC_BYTE_ORDER to be LITTLE_ENDIAN.
+   If the Makefile variable ${CALC_BYTE_ORDER} is empty, then the CPP
+   symbol CALC_BYTE_ORDER will set to the CPP symbol BYTE_ORDER as
+   defined by some system include file (if the Makefile can find such
+   an include file), or the Makefile compiling endian.c and hopefully
+   using that result to set CPP symbol CALC_BYTE_ORDER.  Regardless of
+   how it happens, the CPP symbol CALC_BYTE_ORDER should end up set in
+   endian_calc.h include file.

+
+    On my fairly complete Cygwin installs, everything compiles,
+    checks, and installs correctly.  My Cygwin is configured
+    in a very standard way (out of the box, using all of Cygwin's
+    defaults).  The install worked on 5 different machines with
+    Cygwin on them: one XP home, one XP professional, and three
+    Vista professionals.
+
+Using the calc Makefile, he did the following:
+
+    make all target=Cygwin
+    make check
+    make install
+
+He also reports:
+
+    Of course, one should be logged in as an Administrator when
+    one builds and installs calc.

-    I had previous stated to this group that I have successfully managed

-    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.

+
+    	calc -D 128
+
+    See the calc man page for details.  One may also set that bit
+    while running calc by way of the config() builtin function:
+
+    	config("calc_debug", 128);

+    Shell evaluation of command line arguments
+    ==========================================
+
+    In most interactive shells:
+
+    	calc 2 * 3
+
+    will frequently produce a "Missing operator" error because the '*' is
+    evaluated as a "shell glob".  To avoid this you must quote or escape
+    argument with characters that your interactive shell interprets.
+
+    For example, bash / ksh / sh shell users should use:
+
+    	calc '2 * 3'
+
+    or:
+
+    	calc 2 \* 3
+
+    or some other form of shell meta-character escaping.
+
+
+    Calc reads standard input after processing command line args
+    ============================================================
+
+    The shell command:
+
+	seq 5 | while read i; do calc "($i+3)^2"; done
+
+	FYI: The command "seq 5" will write 1 through 5 on separate
+	     lines on standard output, while read i sets $i to
+	     the value of each line that is read from stdin.
+
+    will produce:
+
+        16
+	2
+	3
+	4
+	5
+
+    The reason why the last 4 lines of output are 2 through 5 is
+    that after calc evaluates the first line and prints (1+3)^2
+    (i.e., 16), calc continues to read stdin and slurps up all
+    of the remaining data on the pipe.
+
+    To avoid this problem, use:
+
+    	seq 5 | while read i; do calc "($i+3)^2" </dev/null; done
+
+    which produces the expected results:
+
+	16
+	25
+	36
