win32s is still a 16-bit executable system, and the code for generating
loads and stores is different than under MINGW32 or CYGWIN32.  I'd be
surprised if you could get any kind of a gcc program to load under
win32s.

That just means that Wine has a built-in crtdll.dll emulation, and
someone forgot to include a stub for _fpreset.  If you go to the Wine
source code and add such a stub, and there are no other problems, then
you ought to get mingw32 programs to load and run.
