We don't really know, and hopefully the list of original causes is
not that big (once everything is analyzed).

We only barely know the state of the very hacked version in NetBSD,
which is able to compile a few simple pkgs from pkgsrc and for
C++ code totaly breaks exception handling. John is running pkg builds
and can likely report more details (and this is not about pkgs where
the source code just does not deal well with VAX floating point).

Many of the changes between upstream gcc and the NetBSD vax backend are
not understood well and may be totaly wrong (likely because they have
been created many versions back and just dragged along through updates).

This is why I would suggest using the unpatched upstream version as a base,
and get the test suite running as good as possible.
