I'm afraid I do not have good news for you... The Tcl packages in 
sourceware are verbatim copies of the upstream ones from sourceforge. 
All we do is tweak the configury a little bit to enable us to build 
under cygwin and in our source/build environment.

That said, cygwin Tcl/Tk is a bit of a monster. While it builds and runs 
on cygwin, it is *not* a cygwin application. Many things simply will not 
work as a result. When passing paths to any Tcl command, they must be 
Windows-style paths, not cygwin. Exec probably calls the Windows API 
function CreateProcess instead of its POSIX equivalent.

I am sorry, but I do not have a cygwin box or any expertise to be able 
to track this down. I do recall that this subject has come up from time 
to time, and a web search shows a few patches and whatnot that you could 
try.

If you find anything that works, let me know, and I will update our Tcl 
sources.
