When I had move time available (and I hope that this'll be the case
again), I ran a vax-linux-uclibc build every 4h to catch breaking
patches early.

For all others who are thinking about stepping up as a maintainer:
You'll loose eons of time if you don't do something similar,
especially for those targets that have virtually no users. It's quite
time consuming to check the last two months of commits for candidates
that broke your build.

Build often, build automatically, and keep the commit emails. For GCC
as well as the binutils and your libc.

I'm quite interested in the VAX target, specifically the Linux bits
I'm having around, but I'm unsure about my current time constraints.
Right now, I wouldn't do promises on that, but I'd be willing to look
into upcoming problems.

Some SIMH instance with a CURRENT NetBSD would probably be helpful and
if somebody helps me to get a NetBSD up'n'running with SIMH, I'd offer
to put my auto-building scripts in there.  NetBSD is at least a
somewhat complete OS, while Linux is still flanky and needs more work,
especially with GNU libc and TLS...
