Is there any reason you can't just ask for the source?

So I see, right.  Well, I can see that gcc 3.3.2 was configured with

 ../configure --target=arm-linux --disable-shared --with-headers=/home/gerg/new-wave.xscale/linux-2.4.x/include --with-gnu-as --with-gnu-ld --enable-multilib

and if you want to build libgcj it you'll need to do the same, with
the same compiler sources.

Right, becaue you have to compile it as part of the toolchain.

AFAICS there's nothing to stop you from downloading the source of gcc
3.3.2, installing the headers from linux somewhere, and running
configure as above.  That should beuild the lot.

Yes.

I'd build the lot.
