I think you shouldn't care about implementation specific #include <ext/...>.
I'm using libstdc++ and stlport in parallel and have suitable #ifdefs:
#if defined( _STLP_MSVC ) || defined( _STLP_UNIX )
#include <hash_map>
#define sgiext std
#elif defined( __GLIBCXX__ )
#include <ext/hash_map>
#define sgiext __gnu_cxx
#else
#error "sgi::hash_map implementation not available?"
#endif
sgiext::hash_map<...>
