More on 'setup' fails and breaks pre-existing Cygwin installation: now have prompt, but it's ultra-high-response time.

  I notice also that there are already directories in Christopher's  path
called 'bin', 'x11', and 'mksnt'.  [ Light bulbs should be appearing in the
air above heads about now, upon seeing the dreaded letters 'm', 'k' and 's'

  This last one in particular makes me wonder if the Rational tools you have
installed maybe include or are based around the Mortice Kern Systems Unix
toolset.  It's a well-known problem that if you try and run cygwin while
having MKS tools in the $PATH they can sometimes clash.  I'd want to start a
dos command shell, then remove all the crud and set a minimal $PATH, and try
again: something like this at the command prompt might work...

cd C:\cygwin
PATH C:\WinNT\system32;C:\WinNT;C:\WinNT\system32\Wbem
bash --login -i

  Did you notice that it's the same as his $LOGONSERVER?  It shouldn't take
that long to look up a hostname when you're logged on directly at the
keyboard of the domain controller.

  But of all the environment variables, I think this is the one that's doing
the most damage:

---snip from cygcheck.out---

  Ouch.  So everytime Cygwin bash tries to fork a subprocess, it launches it
using MKS sh.  No wonder it loses!

---snip from cygcheck.out---
TERM = `nutc'

  Wouldn't have thought cygwin would make much sense of that either.  

Can't think of a witty .sigline today....
