	* f95-lang.c (gfc_init_builtin_functions): Define BUILT_IN_TRUNC
	and BUILT_IN_TRUNCF instead of BUILT_IN_FLOOR and BUILT_IN_FLOORF.
	* trans-intrinsic.c (build_fix_expr): Change 'op' argument
	to correct enum type.
	(gfc_conv_intrinsic_aint): Likewise.  Clarify comment in front of
	function.  Add default case to switch, deal with FIX_TRUNC_EXPR
	instead of FIX_FLOOR_EXPR.
