I'd be very interested in trying.

However, I have never tried getting a different version of gcc setup for 
a build.
I do have a different NetBSD system on which I do cross-build for VAX, 
since it hasn't worked to do a native build in something like 10 years 
(maybe 15, I can't even remember anymore).

But I would then need to setup that system to do a cross-build for VAX, 
with that cross build containing the new gcc. How do I do that.

And once I've installed that on my VAX, I want to test a native build, 
which means I want the VAX system setup to do a native build using the 
new gcc. Also not sure how I go about that.

I've tried looking at BUILDING before, but couldn't really figure it out 
from that documentation.

Also, are GCC 11.1 for VAX available as a tarball or something from 
somehwere? Or where do I get it?

Sorry, these seem like rather trivial questions, but when it comes to 
building NetBSD I've long since given up on knowing intimate details, 
since the whole setup with build.sh and the cross compiling environment 
just made it all a bit too complicated for me to try and understand (in 
my head, I'm almost still with the old makefile solution, especially 
since I still work on 2.11BSD as well).
