The enclosed patch adds the C99 wide character support to the default
GCC namespace except when using C89.  This enables the wide character
specializations when libstdc++ is built.  However, the patch as it
currently stands introduces four regressions in the libstdc++ testsuite:

FAIL: 22_locale/time_put/put/wchar_t/1.cc execution test
FAIL: 22_locale/time_put/put/wchar_t/10.cc execution test
FAIL: 22_locale/time_put/put/wchar_t/5.cc execution test
FAIL: 22_locale/time_put/put/wchar_t/9.cc execution test

I looked at the first one a bit:

Assertion failed: result1 == L"Sun", file /test/gnu/gcc-3.3/gcc/libstdc++-v3/tes
tsuite/22_locale/time_put/put/wchar_t/1.cc, line 53
FAIL: 22_locale/time_put/put/wchar_t/1.cc execution test

The wchar_t * in result1 is null.  I'm not sure why.

With this change, the testcase will build under HP-UX 11i.  However,
it's not going to fix the problem on earlier HP-UX 11 releases.
