The issue is not new with your patch, but if we can distinguish
compilers based on something like '$CC -V' output or similar, then
these code bits can reliably keep working even with MPI (or other)
wrappers to the compilers. We've moved this way for a couple of
other compilers recently.
Since this is typically a strict improvement, a patch to add support
is fine even without it, but while you're testing anyway, you might
be interested to fix it right away. Your choice.
Thanks,
Ralf
