True, but for 'configure' it's good enough, as we don't need the
latest Bash version.

On Solaris 8 the code finds /bin/bash if it's installed (which is the
normal case), /bin/ksh otherwise (on stripped-down hosts).  On Solaris
2.5, 2.5.1, 2.6, and 7 it finds /bin/ksh, since there's no /bin/bash.
This seems OK to me.  I don't have Solaris 9 beta, nor do I have
Solaris 2.4 or earlier, but I suspect they'll be OK too.

We can't do a perfect job here for all installations; people with
unusual requirements can set CONFIG_SHELL in their environment.

I occasionally use it as a sanity check, to test for program
portability.  I don't normally put it into my PATH.  But I don't think
it'll come into play on normal hosts -- and, so (come to think of it)
perhaps we should not mention the xpg4 directory from the PATH.
