Indeed.  I stand ashamed.

Yes.  Grrr.

It's funny, but it actually seems like replacing /bin/sh.exe with (some
version of) /bin/bash.exe actaully *causes* the error to occur more

I noticed that the started.pdf lists bash 2.04.5, so I built that and ran
the limited test script on it, still fails.  I've been able to cause the
test script to fail quite consistently now on all bash versions:  2.04.5,
2.05b, 3.00.0

Hopefully, later this afternoon, I will pare-down a pair of scripts that I
think is generic enough to consistenly reproduce the problem and post them.

The issue is that expr returns a !0 value (correctly), which is lost to the
shell running configure (fault) and so executes the failure pipe.

All available versions of bash are subject to this failure.
