This assumes that a gcc(1) is available on the system.

% man gcc
No manual entry for gcc

If the system compiler is clang/clang++, then it ought to be
documented better than it currently is.  Ian's suggests for
'clang --help' is even worse

%  clang --help | grep -- -std
  -cl-std=<value>         OpenCL language standard to compile for.
  -std=<value>            Language standard to compile for
  -stdlib=<value>         C++ standard library to use

Does <value> == <language>?
