Actually, this problem turns out to be because you've disabled the
fixincludes code with defining STMP_FIXINC= in gcc/config/m68k/t-mint.

On Linux we need to run the fixincludes code so that it picks up the
correct syslimits.h definitions.

If there's still a problem on Cygwin when removing this STMP_FIXINC=
line, then I think it needs fixing elsewhere for Cygwin.

Can you try building again Vincent without STMP_FIXINC defined on
Cygwin ?
