This is fantastic news, Nick!

Heh.  I wonder if Apple has fixed the EH bugs you mention below in
their local branch of GCC, and they just haven't been rolled back
into the FSF version yet?

Is that just on the Apple platform, or everywhere?  Have you reported
these bugs to GNU through their GNATs system?

I don't see any compile-errors there that aren't supposed to happen.
Link errors are another matter.  The introduction of Python's bool
type has changed the output of some of the runtime tests and the
docstrings need to be updated.

BTW, Nick, I never look at the build page; there's so much output
that it's almost impossible to find errors.  I don't know if it's
useful to you, but I think you might run bjam with

   bjam -d0 all

for that page so that the tests don't run.  The test page can hold the
test run output.  Just a suggestion.

Thanks for all your work on this!
