        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.
