I believe that 3.3 is broken.  In my first attempt at a build with
Steven's patch, I hit the error noted in comment #17.  This occurred
using 3.3 20030420 (prerelease).  I debugged the ICE that occurred
compiling genmodes.c and found that it was due to a miscompiled
switch statement.  I then switched to a different bootstrap compiler
and the build was successful.

It's quite possible that Josef's patch would have fixed the problem
on 3.4 but unfortunately I didn't investigate further.

I have a build of 3.3 in progress with Steven's patch.  Should be done
in a week or so ...

Dave
