Confirmed. Note that GCC is available for non-POSIX platforms though. There
should really be some sort of -posix-std= flag to mirror the -std=cyy flag,
i.e., to tell GCC which version of the POSIX standard to conform to, as opposed
to which version of the C standard. Maybe also recognize the POSIXLY_CORRECT
environment variable that other GNU programs use? Still, when GCC does conform
to POSIX, I agree that it should warn here.
