* c-decl.c (mesg_implicit_function_declaration): Init to -1. (implicit_decl_warning): New function. (implicitly_declare): Use it. * c-typeck.c (build_external_ref): Use implicit_decl_warning to complain about implicit decls of builtins. * c-lang.c (lang_init): Set mesg_implicit_function_declaration based on pedantic && flag_isoc99, if not already set. * c-tree.h: Declare mesg_implicit_function_declaration. Prototype implicit_decl_warning. * gcc.dg/c99-impl-decl-1.c: No longer XFAIL. From-SVN: r35385
