 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.
