Hi, folks,
Building with --enable-build-with-cxx fails to bootstrap as follows:
Comparing stages 2 and 3

After bisecting the svn repository, I tracked the problem down to

Can someone take a look at this please?
I came across this while trying to solve why enable-build-with-cxx
didn't build on Fedora 11. (I have a patch, but I was waiting to track
this down first). Having checked in some of the configure patches for
it, I thought I should isolate the actual broken checkin to make sure it
wasn't me :-)
Thanks,
Jerry
