zsh is slower than bash, but the GNU build system as a whole crawls on Mac OS X
10.1; for example, running ./bootstrap on a libtool CVS checkout takes 90 to 120
minutes.  I would like to profile it and try to locate any bottlenecks we could
smooth out, but I have no reason now to believe that the test suite itself is
doing anything wrong.

I did run the test suite with bash.  I'll analyze the failures and report back
to the list.

It would be about a 50 to 200 line patch against autoconf.texi.  I am happy to
assign copyright to the FSF.

Thank you for making contributing to Autoconf easy.
