Paul,
The real reason we need the case translation is for the links is that if
the user doesn't have "check_case:strict" when installing, but later sets
it, the links will still work.

If "check_case:strict" is in effect, the case translation will fail
anyway.  And if it's not in effect, then the directory existence check
will succeed as well.  So the translation is redundant.  But it doesn't
hurt (maybe slows the script down a bit), and in a post-install script
performance is not an issue, so let's leave it in.

However, this reminds me - we had to turn off "check_case:strict" for the
duration of the script for it to work at all with non-standard file and
directory cases!  Something like

  CYGWIN="$CYGWIN check_case:relaxed"; export CYGWIN

I meant to do this one, but completely forgot.  New version attached.
