c.opt (fgnu89-inline): New option.
* c.opt (fgnu89-inline): New option. * c-opts.c (c_common_post_options): Set default value for flag_gnu89_inline. * c-decl.c (WANT_C99_INLINE_SEMANTICS): Remove. (pop_scope): Check flag_gnu89_inline rather than flag_isoc99 for inline functions. (diagnose_mismatched_decls, merge_decls, start_decl): Likewise. (grokdeclarator, start_function): Likewise. * c-cppbuiltin.c (c_cpp_builtins): Define either __GNUC_GNU_INLINE__ or __GNUC_STDC_INLINE__. * doc/invoke.texi (Option Summary): Mention -fgnu89-inline. (C Dialect Options): Document -fgnu89-inline. * doc/extend.texi (Function Attributes): Explain what the gnu_inline attribute does. * doc/cpp.texi (Common Predefined Macros): Document __GNUC_GNU_INLINE__ and __GNUC_STDC_INLINE__.
