Calling all bored VAX hackers :)

I was wondering if there are any VAX coders on the list who are willing (and brave/strange enough) to poke into gcc internals? I have a (relatively speedy) little VAXstation 4000/90 happily running NetBSD-6, which is built using gcc-4.1. All of the other NetBSD ports have switched across to gcc-4.5, but some changes in 4.5 have caused codegen issues in the VAX backend. Essentially you can cross compile a vax system with gcc-4.5, but the resultant system exhibits certain, shall we say, glitches (most annoyingly in the boot program), and the generated compiler is unable to reliably compile anything. Additionally the gcc DWARF2 stack unwinding for VAX appears to be incomplete, causing issues for C++ exceptions, and potentially making libffi unbuildable on VAX. ( http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=44155 ) The latter point is quite annoying as it blocks building glib2, and any app that depends upon it. I know the VAX is pretty much the poster child for legacy platform nowdays, but from a certain perspective a VAX has similar characteristics to an unusual embedded system, (just built using steam pipes & valves), so should be able to run the same basic apps, tools, and even graphical apps. Besides, to quote Dylan Thomas I feel the VAX should not go gentle into that good night, but rage, rage against the dying of the light :)
