fix fenv exception functions to mask their argument
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
