non-critical impact:

wcslen - incompatible return value on error (NcWn34)

I18N Impacts

Problem description

The Tru64 UNIX and HP-UX error return values for this routine are incompatible.

The wcslen routine finds the length of a wide-character string. On Tru64 UNIX, when passed a NULL pointer, wcslen returns -1 cast to size_t. On HP-UX, for the same situation, wcslen returns 0 cast to size_t.
