puzzles/windows.c
Simon Tatham 15f70f527a Dariusz Olszewski's changes to support compiling for PocketPC. This 
is mostly done with ifdefs in windows.c; so mkfiles.pl generates a
new makefile (Makefile.wce) and Recipe enables it, but it's hardly
any different from Makefile.vc apart from a few definitions at the
top of the files.

Currently the PocketPC build is not enabled in the build script, but
with any luck I'll be able to do so reasonably soon.
