I have tested builds of gmp/mpfr/mpc on :
1) x86_64-Linux2.6.18-274.17.1.el5
2) x86_64-Linux2.6.32-220.4.1.el6.x86_64
3) sparc-SunOS5.10
4) plus various others ( ppc970 et al )
seen no major problems thus far. Also, gmp,mpfr,mpc all build fine
with all tests passed even on a very very old :

So I have not seen a gmp mpfr or mpc issue, anywhere.
HOWEVER, I do use the very latest revs of mpfr,gmp and mpc.
