Wlong-long only depends on other flags if it is uninitialized. * c-parser.c (disable_extension_diagnostics): warn_long_long is the same for CPP and FE. (restore_extension_diagnostics): Likewise. libcpp/ * init.c (cpp_create_reader): Wlong_long is disabled by default. * expr.c (cpp_classify_number): Give different messages for C and C++ front-ends. cp/ * parser.c (cp_parser_check_decl_spec): Drop redundant flags. * error.c (pedwarn_cxx98): New. * cp-tree.h (pedwarn_cxx98): Declare. testsuite/ * gcc.dg/wtr-int-type-1.c: Use two dg-warning to match two messages. Test for "long long" in system headers. * gcc.dg/c99-longlong-2.c: New. * g++.dg/warn/pr13358.C: New. * g++.dg/warn/pr13358-2.C: New. * g++.dg/warn/pr13358-3.C: New. * g++.dg/warn/pr13358-4.C: New.
