The C standard doesn't require a compiler to recognize the FENV_ACCESS pragma, but if the compiler does not recognize it, then it must assume that this pragma is ON (otherwise the generated code can be incorrect). That's why I suggested that -frounding-math should be the default. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34678
