    compat.h: Ensure check for `__STDC_VERSION__` is not attempted for c++.

    `__STDC_VERSION__` is specific to C but up until gcc 16, the g++ compiler
    also defined it.  With g++ 16.0 it's no longer defined (which is the correct
    behavior) so compiling channelstorage_cpp_map_name_id.cc fails.  The
    check for `__STDC_VERSION__` in compat.h is now skipped if we're compiling
    a C++ source file.

    Resolves: #1903
