- move stlport headers to the c++ directory - add a specific _reactos.h configuration file for stlport - add cerrno to c++ headers - __declspec(nothrow) must be placed before calling convention with msvc. GCC doesn't care. We now use our headers with both msvc and gcc. svn path=/branches/cmake-bringup/; revision=49565
