Wow!  You nailed it dead-on.  The version of expr that was installed
with BeOS PPC R5 is from GNU sh-utils 2.0.  This is the broken version.
I replaced it with v1.16 from the GeekGadets project.  At least the
first test seems to function properly.  I will re-run the autoconf
testsuite to see if (at least some) problems go away.

Thank you for your help,
