Regtested on FC5/x86_ia64 - OK for trunk, and 4.2?
In 4.2, the fmod intrinsic is still protected by
flag_unsafe_math_optimizations. For your fortran patch to be effective
on 4.2, fmod patch
(http://gcc.gnu.org/ml/gcc-patches/2006-10/msg01209.html) needs to be
backported to 4.2. [Patch was OK'd for mainline].
Roger, is fmod patch also OK for 4.2?
Ah yes, you are quite right. This is not exactly a bug fix, is it?
OK for trunk, then? :-)
