(gnat_write_global_declarations): New prototype. * gcc-interface/utils.c (type_decls): Rename back to... (global_decls): ...this. (gnat_pushdecls): Revert previous change. (create_var_decl): Do not output global variables. (note_types_used_by_globals): Rename back to... (gnat_write_global_declarations): ...this. Output variables on the global_decls vector. * gcc-interface/misc.c (gnat_parse_file): Adjust to above renaming.
