    [libstdc++] [testsuite] intro/names.cc: undef func on vxw7krn
    
    The '#define func' added in 2021, to test that system headers don't
    violate the user namespace, exposes such a bug in the vxworks sysLib.h
    header, so add yet another such annotated workaround.
    
    
    for  libstdc++-v3/ChangeLog
    
            * testsuite/17_intro/names.cc: Undef func on vxworks >= 7 in
            kernel mode.
