Patch: FYI: fix TransformerImpl buglet

[Tom Tromey]

I'm checking this in to Classpath, gcc svn head, and the RH 4.1
branch.

This fixes PR 29362, a TransformerImpl buglet pointed out by the
Eclipse CDT.  I'm not completely sure that this is the best fix, but
we did test it against the CDT and it removed the particular failure
we were seeing.

FYI there's a self-contained test case in the PR.
