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>?
a quick google search turns up the following additional information:
"clang supports the -std option, which changes what language mode clang
uses. The supported modes for C are c89, gnu89, c99, gnu99, c11, gnu11,
c17, gnu17, and various aliases for those modes. If no -std option is
specified, clang defaults to gnu11 mode. Many C99 and C11 features are
supported in earlier modes as a conforming extension, with a warning.
Use |-pedantic-errors| to request an error if a feature from a later
standard revision is used in an earlier mode."
