I should have mentioned that the sstream file does not exist in any
official release of GCC 2.95, it was added to FreeBSD's unofficial GCC
2.95.4 release, which is why I reported it here.

The file did exist in the GCC repository briefly between April 2000 and
Feb 2001 but was not included in any release AFAICT.

It's very unlikely that the patch will be applied to the official GCC
tree, since the file has been removed and is only in the Attic:
http://gcc.gnu.org//cgi-bin/cvsweb.cgi/gcc/libstdc++/Attic/sstream

However, if FreeBSD are going to ship the file I believe it should be
patched so it performs reasonably.
