[committed] libstdc++: Fix test that fails due to name clash with old glibc [PR107979]
Commit Message
Tested x86_64-linux. Pushed to trunk.
-- >8 --
This test was recently modified to check that the library doesn't use
__unused anywhere, because that's a macro in newlib. But it's also a
macro in old versions of glibc, so the test now fails for those targets.
Disable that check for those targets as well as for newlib.
libstdc++-v3/ChangeLog:
PR libstdc++/107979
* testsuite/17_intro/names.cc: Do not check __unused on old
Glibc versions.
