c-tree.h (struct c_declspecs): Remove typedef_decl.

	* c-tree.h (struct c_declspecs): Remove typedef_decl.  Add
	typedef_p and typedef_signed_p.
	* c-decl.c (shadow_tag_warned): Check typedef_p, not typedef_decl.
	(grokdeclarator): Don't use typedef_decl for warn_deprecated_use.
	Check typedef_p and typedef_signed_p, not typedef_decl.
	(grokfield): Check typedef_p, not typedef_decl.
	(build_null_declspecs): Initialize typedef_p and typedef_signed_p,
	not typedef_decl.
	(declspecs_add_type): Set typedef_p and typedef_signed_p, not
	typedef_decl.

testsuite:
	* gcc.dg/bitfld-9.c: New test.
