re PR c/26494 (-pedantic-errors can be overridden by -W*)
2007-02-15 Manuel Lopez-Ibanez <manu@gcc.gnu.org>
PR c/26494
* doc/invoke.texi (Warning Options): Remove
-Werror-implicit-function-declaration.
(Wimplicit-function-declaration): Update description.
* opts.c (common_handle_option): Move handling of -Werror=* to...
(enable_warning_as_error): ...here.
* opts.h (enable_warning_as_error): Declare.
* c-decl.c (implicit_decl_warning): Unless
-Wno-implicit-function-declaration is given, emit a pedwarn if
-std=c99 or emit a warning if -Wimplicit-function-declaration.
* c.opt (Wimplicit-function-declaration): Replace
mesg_implicit_function_declaration with
warn_implicit_function_declaration.
* c-opts.c (c_common_handle_option):
-Werror-implicit-function-declaration is exactly equal as
-Werror=implicit-function-declaration.
(set_Wimplicit): Replace mesg_implicit_function_declaration with
warn_implicit_function_declaration.
(c_common_post_options): -Wimplict-function-declaration is enabled
by default by -std=c99, otherwise is disabled by default.
* c-objc-common.c (c_objc_common_init): Remove flawed logic.
