  To: gcc-patches, libstdc++


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.

Regstrapped on x86_64-linux-gnu.
Tested on arm-vxworks7 (gcc-12) and arm-eabi (trunk).  Ok to install?

for  libstdc++-v3/ChangeLog

	* testsuite/17_intro/names.cc: Undef func on vxworks >= 7 in
	kernel mode.
