My mistake, the message is there in the log file on Linux but the test
still passes for some reason:

/tmp/ccIqVtui.o: In function `test01()':
/proj/opensrc/nightly/src/trunk/libstd
++-v3/testsuite/27_io/objects/wchar_t/9661-1.cc:48: warning: the use of
`tmpnam' is dangerous, better use `mkstemp'^M
output is:
/tmp/ccIqVtui.o: In function `test01()':
/proj/opensrc/nightly/src/trunk/libstdc
++-v3/testsuite/27_io/objects/wchar_t/9661-1.cc:48: warning: the use of
`tmpnam' is dangerous, better use `mkstemp'

PASS: 27_io/objects/wchar_t/9661-1.cc (test for excess errors)
