re PR preprocessor/25717 (-dD does not list all defined macros (in particular, __STDC__))
PR preprocessor/25717 * init.c (cpp_init_builtins): If __STDC__ will not change value between system headers and other sources, define it as a normal macro rather than a builtin. * macro.c (_cpp_builtin_macro_text) <case BT_STDC>: Only check cpp_in_system_header condition. From-SVN: r110144
