possible bug in gcc 2.95.1 (C++)

["Michael (Micksa) Slade" <mslade at cit dot nepean dot uws dot edu dot au>]

I don't know enough about C++ to know if this is a bug or not, but I
can't figure it out.  If this is my fault let me know :)

Version: gcc 2.95.1
OS: Linux 2.2.12, glibc 2.1 (self-built system)

How to reproduce bug:

get ftp://ftp.nllgg.nl/pub/SGMLtools/v2.0/source/sgmltools-2.0.2.tar.bz2
and try to compile it :)

You should get a bunch of errors about templates already being
instantiated.  This is one bug, I think - adding explicit instantiations
fixed the problem; should this be necessary?

Then, apply the attached patch and re-make.  You should then get two
errors stating that certain templated members can't be found, even
though as far as I can tell they're there.
