Solaris is well(?)-known for this kind of failure mode (see also
/usr/ucb/bin/cc, IIRC, and everybody's favorite utility, Solaris tar).

I think we're reasonably good about keeping bash-isms out of our
configure script, but I don't think ksh is close enough to Bourne sh
to work.  And there's no guarantee that Solaris's ksh is the same as
other ksh's.  It might even be buggy. ;-)

I would try to force a Bourne shell.  I'll see if I can find a ksh
somewhere and try that on Linux and Mac OS X.
