Bash fails in exactly the same way that sh does.  I was able to get
the real output that I should have gotten originally.  :)

That was my guess.  But since this was the cygwin installer run off 
of the cygwin site I thought I'd mention it, if for no other reason 
than tracking purposes.  Maybe there's a problem with the installer /
postinstall script when downgrading? Or perhaps that's intended 
behavior.  It was just surprising.

And... it didn't run again when re-upgrading just bash to the new
(broken) version so we had to manually copy bash.exe to sh.exe.
