Getting started with merged GCJ

[Jim Mayer <jim at pentastich dot org>]

Hi all,

First... I really, REALLY, TRULY (I promise) looked through the
archives, FAQs, etc. before I sent this note!!!  Really.... I promise!

Anyway, I'd very much like to experiment with the new trunk version of
GCJ, but I'm not having much luck building it.  I was attempting to
follow the directions at <http://gcc.gnu.org/java/build-snapshot.html>
but that resulted in compilation errors yesterday (a warning) and the
following messages with a version I updated last night:

/home/jim/src/compile/objdir/gcc/gcj

Illegal instruction
Please submit a full bug report,
with preprocessed source if appropriate.

I see references in the list archives to "java maintainer mode",
"ecj.jar", scripts that Tom Tromey wrote, etc... but I haven't seen any
recommendations on how to get started.

Help!

Thanks.
