Ken, thanks for replying.

These are the DLL's in the strace output, expanded with "ldd."  I
don't see anything out of the ordinary.

Is there a list of DLL's known to cause problems with Cygwin?

How would I better isolate the problem causing DLL?  Specific verbiage
in the strace output?  Should I run strace with the "-a" option?
