does GMP "make check" pass? I just tried compiling GMP 5.0.3 and "make check"
fails:

PASS: t-div

This is with the default GCC version (4.2.1). I'll now try with egcc (4.2.4).

Note that this error is mentioned on the GMP status page:
http://gmplib.org/devel/testmachines/check/failure/loulou.esiee.fr:64

but this issue is not mentioned on http://gmplib.org/#STATUS, where there is
an extra closing parenthesis in "strike this bug.)"
