The regression tests are regression tests, and not conformance tests for any particular standard. FreeBSD prints "Unknown error: x", not "No error" like MSVC, and not "Error x" like Solaris. FreeBSD 4.8-RELEASE and 5.0-CURRENT pass the tests. $ uname -srm FreeBSD 5.0-CURRENT i386 $ make cc -O -pipe -mcpu=pentiumpro test-strerror.c -o test-strerror cc -O -pipe -mcpu=pentiumpro test-wcschr.c -o test-wcschr cc -O -pipe -mcpu=pentiumpro test-wcscmp.c -o test-wcscmp cc -O -pipe -mcpu=pentiumpro test-wcslen.c -o test-wcslen cc -O -pipe -mcpu=pentiumpro test-wmemchr.c -o test-wmemchr cc -O -pipe -mcpu=pentiumpro test-wmemset.c -o test-wmemset for p in test-strerror test-wcschr test-wcscmp test-wcslen test-wmemchr test-wmemset; do /home/tim/p4/wchar/src/tools/regression/lib/libc/string/$p; done PASS strerror() PASS strerror_r() PASS wcschr() PASS wcscmp() PASS wcslen() PASS wmemchr() PASS wmemset() TimReceived on Sun Apr 20 2003 - 22:34:05 UTC
