Someone must apply the change, make a patch, and test the results.

OK, I see.  I was wondering whether this was a theoretical problem that
might just come up or something real.  I was also wondering whether this
was relevant to free software.

Given that this looks real, and it is relevant to free software, I can
have a look.  However, I can't go back in time, so any change that I make
will not affect the gcj that's in distros for some time to come.
