The libstdc++ comes with gcc 2.95.2 is not yet ISO C++ Compliant. I've
ported STLport-4.0 to DJGPP and I've tested your program with STLport-4.0.
It is ok. You can find DJGPP port of STLport-4.0 (source no binary, sorry)
in ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2tk/stlp40s.zip. However,
size of executable when using stlp40s instead of libstdc++ will be bigger.
You may need to prepare to sacrifice.
