As far as I know, 3.3 is OK.  However, the current release branch (3.2)
is still broken and I doubt it can be fixed without an unacceptable
amount of changes to real.c.  The 3.2 branch can be built with the
native compiler.  3.3 currently can't.

At some point, I plan to change vax.h back to not using the emulator
on the 3.2 branch.  This was the way it was before 3.1/3.2.  This will
fix the problem for native compilers but it won't be possible to build
a working cross compiler.
