Hi David,

thanks for posting the cygwin install instructions and for the diff.
I've entered this change (and a couple of other $(exeext)) into the
gm2/Makefile.in and rebuilt the latest cvs tarball.  I'll include
these instructions into the documentation and reference them from the
web page in due course.

Incidentally, how difficult would it be to generate a Windows binary
package for GNU Modula-2 (say for cygwin - rather than MinGW - at
present)?  I've no knowledge about how packages are generated
for XP,

regards,
Gaius
