what's up with the 22_locale fails on 64 bit hosts?

Yo. Both of these test results show some similar fails:

http://gcc.gnu.org/ml/gcc-testresults/2003-04/msg00638.html
http://gcc.gnu.org/ml/gcc-testresults/2003-04/msg00642.html

In particular, 

FAIL: 22_locale/codecvt/always_noconv/wchar_t/3.cc execution test
FAIL: 22_locale/codecvt/encoding/wchar_t/3.cc execution test
FAIL: 22_locale/codecvt/encoding/wchar_t/wrapped_locale.cc execution test

FAIL: 22_locale/ctype/widen/wchar_t/2.cc execution test
FAIL: 22_locale/ctype/widen/wchar_t/3.cc execution test

Any chance one of y'all could do some analysis on this? I'd appreciate it.

thanks,
