Q about g++-3 and template instantiation

["Dan E. Kelley" <kelley@Phys.Ocean.Dal.CA>]

I'm the author of `gri' (gri.sourceforge.net), which is packaged in
Debian.  I'm porting gri to g++-3 in preparation to Debian's (and everyone
else's) eventual move to that compiler and I'm having some problems.
Perhaps someone on this list could help?  I hope it's not rude of me to be
asking this here, but perhaps asking the question will help others in the
Debian project.  My question is below.

Attached is a 6-line C++ test program (which does nothing more than
instantiate templates) that compiles in g++-2, with

        g++ -c test-template.cc

but for which g++-3 yields the error messages:

        test-template.cc:4: non-template used as template
        test-template.cc:6: non-template used as template

QUESTION: am I doing something wrong?
