I believe it lives in
	src/contrib/libstdc++/include/std/std_sstream.h
in the FreeBSD repository, and in
	 gcc/libstdc++-v3/include/std/std_sstream.h
in the gcc repository.  It is subsequently installed as
/usr/include/g++/sstream when libstdc++ is installed.

I glanced at the gcc repository[1] and FreeBSD 5.2-CURRENT, and it
appears that the file has changed significantly since gcc 2.95.
However, AFAICT, it still has the same bug.  Unless I'm missing
something, you probably want to report this problem to the gcc
folks.  I'm not the right person to say whether the fix will find
its way back into FreeBSD 4.X, though.
