This seems to be, on the face of it, the same problem that bit the WinCVS users - WinCVS looks for a tcl84.dll in the PATH and automatically dynamically loads it, and if it happens to be a Cygwin-compiled one, it hangs. This also changed after 1.5.6 - before that, it would "work", for some definition of "working".

Dynamic loading of cygwin1.dll has been broken for a very long time.  That
doesn't mean it cannot be fixed.  Just that figuring out what changed 
between 1.5.5 and 1.5.7 and reinstating it would not be a fix.  It's 
the Cygwin DLL initialization that needs attention really.  But I do 
expect that everyone would like it if someone got this working again. :-)
