fesetround.c is a wrapper to do the arch independent argument check (on archs where rounding mode is not stored in 2 bits __fesetround still has to check its arguments) on powerpc fe*except functions do not accept the extra invalid flags of its fpscr register the useless FENV_ACCESS pragma was removed from feupdateenv
