The patch passed "make bootstrap" on i386 and succesfully compiled
attached builtins-46.c with and without "-ffast-math". OK for mainline?
I forgot to say, that functionality was tested by comparing output of
testcases with (among others) numbers 0.49, 0.5, 0.51, 1.5, -2.5 with
and without "-ffast-math". Also povray-3.5 (which uses these functions a
lot) was built and I could not spot any differences on produced
raytraced pictures, when povray was compiled with and without
-D__NO_MATH_INLINES.
