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those systems, we just elected to remove the somewhat out of
date and awkward `win32.mkdef` and related win32 references.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.

-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.
-
-NOTE: The use of DJGPP and this method has been deprecated.
-      It may go away once the Windows 11 methods are stable.
