There have been several issues with exception handling in older compilers.
If it was easy for you to try gcc 2.95.2, and an updated libstdc++, that
would probably be no bad thing.

Also you may want to use the version of the host sources in anonymous CVS;
this change may help you:

2000-08-18  Bart Veer  <bartv@redhat.com>

        * base.cxx, build.cxx, cdl.hxx, cdlcore.hxx, component.cxx,
        config.cxx, database.cxx, dialog.cxx, expr.cxx, interface.cxx,
        interp.cxx, option.cxx, package.cxx, parse.cxx, value.cxx,
        wizard.cxx
        Remove C++ exception specifications, because they cause problems
        with some versions of the tools.
