new g++ errors prevent bootstrapping.

[Robert Lipe]

Thursday afternoon, this was a non-problem.   Sunday evening, it was
a problem.   Both JP and I have seen this so I don't think it's something
funky about my specific setup.

I'm seeing lots of g++ errors on OpenServer that have basically the same
shape.  Top-level libraries won't build, though the stuff in libgcc2 is
fine..  I don't see this from the same source tree on Linux/x86.

$ make check-g++ RUNTESTFLAGS="old-deja.exp=crash*"

Looking at the first one of those errors, I see:

I'm now seeing literally hundreds of errors of various types - all in
g++ - during a build and testsuite run.   Here are some of a slightly
different flavor.

CVS doesn't show my tree as containing doodoo in generated files like
parse* and I have gone through the bootstrapping exercise so I don't
think it's a case of the native compiler miscompiling things.

Any hints where I should go digging for this?

Thanx,
