The first exe you speak of just generates config.h, but you can also
create that header file my hand if you wish.  Try making one the usual
way, and look for #defines and const declarations and such that might need
to be changed for the PocketPC platform.  That will probably be a
trial-and-error process, but if you make it work, it would be very cool to
update configurator.c with your findings.

I would expect floating point emulation to be available, perhaps as a
linker option, but I'm just guessing.
