------- Comment #10 from rguenth at gcc dot gnu dot org 2008-10-15 22:14 ------- The default of -fno-rounding-math is chosen with the reason that this is what a compiler can assume if #pragma STDC FENV_ACCESS is not turned on.
What you may request instead is an implementation of FENV_ACCESS up to that point that we issue a fatal error whenever you try to turn it on. Or at least a warning by default. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34678
