        PR 30551
        * doc/invoke.texi (Wmain): Update.
        * c-decl.c (start_decl): warn_main is only 0 or 1.
        (start_function): Likewise. Fix formatting.
        (finish_function): Delete redundant warning.
        * c.opt (Wmain): Add Var(warn_main) and Init(-1).
        * c-opts (c_common_handle_option): -Wall only has effect if
        warn_main is uninitialized. OPT_Wmain is automatically
        handled. -pedantic also enables Wmain.
        (c_common_post_options): Handle all logic for Wmain here.
        * c-common.c (warn_main): Delete.
        (check_main_parameter_types): Make pedwarns conditional on
        OPT_Wmain.
        * c-common.h (warn_main): Delete.
cp/     
        * decl.c (grokfndecl): Call check_main_parameters_type only if
        -Wmain.
