I'm seeing a similar problem with python and 1.5.19 and also tried the 
snapshot of 22-May.

CYGWIN_NT-5.1 kleckner2 1.5.20s(0.155/4/2) 20060522 00:51:23 i686 Cygwin

A simple test case doesn't fail in dlopen().

My code is not simple but has been working prior to the most recent 
update (which also updated python and other packages).
A downrev of python does not make the problem go away.  If I downrev 
cygwin, I get complaints about missing entry points.

What do you recommend as the best way to isolate this?
