Add a '-v' to your command line, and you'll see that that directory isn't
searched:
#include <...> search starts here:
/usr/include/g++-v3/ext
/usr/include/g++-v3
/usr/include/g++-v3/i386-linux
/usr/include/g++-v3/backward
/usr/local/include
/usr/lib/gcc-lib/i386-linux/3.0.2/include
/usr/include
and that's the correct behaviour: "dpkg -S /usr/include/g++-3/hash_map"
shows that that "hash_map" is part of the "libstdc++2.10-dev" package which
is for use with g++ 2.95, not with g++ 3.

I get the same behaviour with unstable.
There is a /usr/include/g++-v3/ext/hash_map that's part of "libstdc++3-dev"
which is for use with g++ 3, but that file says
/* NOTE: This is an internal header file, included by other STL headers.
* You should not attempt to use it directly.
*/

It may be that that is the proper way to do it; I'm not familiar enough with
STL to know. Perhaps someone on debian-gcc can comment on this?
