Some xmaxima files for windows checked in to CVS



I have created a directory interfaces/xmaxima/win32 in CVS with
the files needed to build and support xmaxima.exe on windows.

In contains winkill.c and tclwinkill.c from the gcl tree, and
a Makefile.in with the rules to build winkill.exe, tclwinkill.dll
and xmaxima.exe.  You need to cd in to the directory and type 
make, and there is no install target, but it is a start.

I tried to put together a Makefile.am with conditional compilation,
but have given up for the moment.
