c-decl.c (finish_decl): Set DECL_DEFER_OUTPUT on tentative file-scope definitions.
* c-decl.c (finish_decl): Set DECL_DEFER_OUTPUT on tentative file-scope
definitions.
* toplev.c (rest_of_decl_compilation): Check DECL_DEFER_OUTPUT to
recognize a tentative definition. Lose obsolete code.
* toplev.c (wrapup_global_declarations): Don't emit DECL_COMDAT
variables unless necessary, either.
