No.  I'm not even sure why it was put in.  I don't remember being involved in
this particular instance.  Sorry.

Fair enough.  I told you in December I would try and devote time to cleaning
these up.  The issues in the two emails I sent this morning are the only
stumbling blocks I see to having an complete ARM ELF compiler for Linux that
builds from the source tree without patches.  I'll continue to devote time to
this, as I can, until we reach that goal.  Comments, hints, and suggestions are
welcome though.  I'm also close to having libgcj compile to completion, which
would make the java compiler useful on the ARM.  That's a little further off
