Hrm, looks like the G++ folks have changed their mind again about
how their compiler is supposed to work.  I don't have RH 7 yet, and
probably won't upgrade to it before they come out with 7.1 (which
should contain a less-broken compiler.)

To fix the problem will probably require rewriting the template
code (again), and I'm not sure exactly how to go about that at
this time.

You could try changing the makefiles to use kg++ instead of
g++, but I'm not sure if that will work or not...
