The VAX support in gcc is probably better now that it have been in quite
a while. Big kudos to the people (I suspect Matt Thomas) for getting
that done. However, gcc itself is getting so slow it's just not fun to
even joke about anymore.
But apart from that, it's my view that the kernel and various subsystems
around that have degenerated since 4.0.

That's all true for NetBSD CVS, but not for upstream GCC. The recently
introduced new register allocator needs (for VAX: probably only minor)
changes. These haven't been done up to now and the VAX port, once
again, is a target proposed for removal in upstream GCC.

There was a tip[1] on the GCC list what's needed to get done. Maybe
I'll try another NetBSD installation (in simh) in a few days and try to
bulid GCC with the proposed changes.

I have gcc-trunk working with all the changes.  But with all the changes
it's a massive diff (3K+ lines) and the needed ChangeLog entry scares me.
