Hmm.  If so, it's quite a weird way to handle this, rather than
loading the modules with full path.

Is that a Tcl "feature", or is it how certain Tcl apps are implemented?
I can't really believe the former...

Assuming I create a Cygwin snapshot adding a call to SetDllDirectory in
the next couple of days, would you be willing to test if your Tcl stuff
still works?


Thanks,
