http://gcc.gnu.org/onlinedocs/gcc/C-Dialect-Options.html#index-std-98 This is covered in the manual. The default for C is gnu89 and the default for C++ is gnu++98. The --help output is not supposed to be a substitute for proper documentation, it's just a brief summary. To list predefined macros, use -dM with an empty input file, e.g. "gcc -dM -E - </dev/null". -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37820
