	checking of symbol attributes for attribute declaration
	statements.
	* decl.c (attr_decl1): Call gfc_add_attribute for each of -
	(gfc_match_external, gfc_match_intent, gfc_match_intrinsic,
	gfc_match_pointer, gfc_match_dimension, gfc_match_target):
	Remove spurious calls to checks in symbol.c.  Set the

	checking.
	* gfortran.h:  Add prototype for gfc_add_attribute.
