I should have pointed out that before making any changes I couldn't use
Boost with GCC 3.4 on FreeBSD 4.x. FreeBSD 4 does not support wchar_t
(and therefore doesn't support std::wstring or std::wstreambuf) but Boost
was failing to detect this because the select_stdlib_config.hpp file
didn't match __GLIBCPP__ and so didn't include libstdcpp3.hpp.

An alternative approach to the patches I sent would be to include
the same libstdcpp3.hpp file for both __GLIBCPP__ and __GLIBCXX__
and make that file handle both cases. I don't know which is preferred.

Another related patch is attached to this mail, changing the file
libs/config/test/config_info.cpp so it calls PRINT_MACRO with the new
GLIBCXX macro names as well as the old GLIBCPP ones.
