(grok_declarator, start_function): Call permerror_opt instead of warn_defaults_to. (store_parm_decls_oldstyle): Call permerror_opt for OPT_Wimplicit_int. gcc/testsuite/ * gcc.dg/permerror-default.c (implicit_int_1, implicit_int_2) (implicit_int_3, implicit_int_4): Expect new permerror. * gcc.dg/permerror-system.c: Expect a single new permerror. * gcc.dg/Wimplicit-int-1.c: Compile with -fpermissive due to expected warning. * gcc.dg/Wimplicit-int-4.c: Likewise. * gcc.dg/Wimplicit-int-1a.c: New test.
