[boost] [patch] GCC 3.4 removed __GLIBCPP__ macro

Hi, The version of libstdc++ that ships with GCC 3.4 has changed a number of macro names, so the boost/config/stdlib/libstdcpp3.hpp file no longer works. __GLIBCPP__ -> __GLIBCXX__ _GLIBCPP_USE_WCHAR_T -> _GLIBCXX_USE_WCHAR_T _GLIBCPP_USE_LONG_LONG -> _GLIBCXX_USE_LONG_LONG The attached patch adds a check for __GLIBCXX__ to select_stdlib_config.hpp and includes a new libstdcxx3.hpp file if it's defined. That new file is also attached. If noone's already working on this, is my approach the best one? jon -- "Surrealism aims at the total transformation of the mind and all that resembles it" - Breton
