Making strings of arbitrary character types

[Nick NoSpam]

I read the section: "Making strings of arbitrary character
types" (http://gcc.gnu.org/onlinedocs/libstdc
++/21_strings/howto.html#5) ; very helpful.

With GCC 3.3.2, the section is spot on--trying something like
basic_string<unsigned char>--yields linker errors about missing
char_traits for unsigned char.

But with GCC 3.4.2, basic_string<unsigned char> works out of the box.

Does 3.4.2 provide a specialization for this type (and possibly others)?
If so, is it intentional (ie. can I expect it in future versions)?  Or
should I specialize char_traits for portability?
