[boost] [test] failure of basic_cstring_test with GNU libstdc++

Boost.Test library test basic_cstring_test.cpp fails to compile
on many (all?) platforms using GNU libstdc++. Follows reproducer
and the results of compiling it with GNU 4.3.0 and 3.4.6.

Replacing 'utf::basic_cstring<CharT>::size_type' with 'std::size_t'
in libs/test/test/basic_cstring_test.cpp makes the problem go away.

Is it a known problem in GNU libstdc++? Does the fact that the
implementation does not have to provide specializations of
basic_string<> other than for 'char' and 'wchar_t' makes x.cpp
below illegal?

Thanks,
  Boris
