drop support for DJGPP and drop support for win32
Support for win32 and DJGPP has been dropped. Calc version 2.14.3.5 was the last to make references to win32 and make references to DJGPP. Future versions of calc may work under those systems, we just elected to remove the somewhat out of date and awkward `win32.mkdef` and related win32 references. If you are a win32 user, please feel free to create a win32 target in Makefile.target and submit as a pull request. If you are a DJGPP user, please feel free to create a DJGPP target in Makefile.target and submit as a pull request. Until someone can test such systems, we prefer to wait until someone is able to test and supply a pull request.

is a fork of Cygwin. In `Makefile.config`, when the OSNAME is "Msys",

the Cygwin target it set. MSYS2 Software Distribution users should be

sure that the following command prints "Msys".

Much earlier (2001?) Thomas Jones-Low (tjoneslo at softstart dot com)
|
||||
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.
|
||||
|
||||
NOTE: The use of win32_hsrc and this method has been deprecated.
|
||||
It may go away once the Windows 11 methods are stable.

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

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.
