Hi Geoff ;^),

Recently while trying to create a set of headers
to allow gcc to work with msvcrt.dll, I discovered
that msvcrt.dll returns div_t, and ldiv_t in
registers.

I was kind of surprised when I realized that the
cygwin32 gcc default is -fpcc-struct-return.

I believe that VC++ normally returns short structs in
registers, (I could be wrong ;^) but if that is the case
shouldn't the gcc default be -freg-struct-return?
