re PR c/30551 (-pedantic does not include -Wmain, but -pedantic-errors does make -Wmain cause error messages)
2008-08-13 Manuel Lopez-Ibanez <manu@gcc.gnu.org>
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.
