Subject: Warning fixes:
X-Git-Tag: prereleases/libstdc++-2.92~5392
X-Git-Url: https://gcc.gnu.org/git/?a=commitdiff_plain;h=20217ac1248ad3d2a3cc1ddd75b86468ee8fc97c;p=gcc.git

Warning fixes:

	* c-decl.c (set_current_function_name_declared, anon_aggr_type_p,
	lang_expand_stmt): Mark parameters with ATTRIBUTE_UNUSED.

	* c-parse.in (stmt): Delete unused variables.

	* convert.c (convert_to_vector): Likewise.

	* gensupport.c (process_rtx): Declare attr as `rtvec' not `rtx'.

	* tree.c (finish_vector_type): Prototype.
