Indeed and the magic combination varies from platform to platform. To run on 
Gentoo Linux with gcj 4.1.0, you need a patch. Maybe that got checked in for 
4.1.1, I don't know.

Anyway, unless you have lots of time to explore, the gcc/gcj 3.4.6/Ubuntu 
6.06 combination seems to work well. If you find another one, let us know.

For the record, these are the combinations known to work:

   - Mac OS X 10.3/10.4 PowerPC: gcc/gcj 3.4.x with x >= 3
   - Mac OS X 10.3/10.4 PowerPC: gcc/gcj 4.1.0 built with darwinports
   - Mac OS X 10.4 Intel gcc/gcj 4.0.2 with patches by Sandro Tolaini
   - Linux Gentoo 2005: gcc/gcj 3.4.x with x >= 2
   - Linux Gentoo 2005: gcc/gcj 4.1.0 with a patch from Bryce McKinley
   - Linux Ubuntu 6.06: gcc/gcj 3.4.6
   - FreeBSD: gcc/gcj 4.1.0
   - Windows: gcc/gcj 3.4.x with x >= 2

In addition, if you hit the dreaded 'too many root sets' error, you might 
want to closely follow the instructions in PyLucene's INSTALL and define 
LARGE_CONFIG in gcj's boehm-gc/include/private/gc_priv.h. It's been a problem 
on Mac for a long time and it just happened to me on Windows as well.
Building gcc/gcj for Windows is best done on Linux via a cross-compiler and 
can take many trials and errors before functioning. For all gcc/gcj building 
questions, please refer to the java at gcc.gnu.org mailing list.
