Ok, I applied one change to fenv.c/fenv.h which seems to solve the
problem, but I have no idea why: I still don't understand why using an
int with an instruction expecting a word can work, but I don't know
much about gcc inline asm syntax anyway. The change is taken from
FreeBSD, from which the original file is coming from, and it looks
like we should do the change anyway.

Another problem is that I can't make nose test find any test under
cygwin (I applied the change to both trunk and 1.1.x branches, and on
1.1.x, all but one tests pass, the failure not being related to this).

cheers,
