I can now confirm that there is a problem with the eCos Configuration
Tool and version 1.5.19 of the Cygwin DLL. The eCos Configuration Tool
fails during initialisation inside a call to pthread_key_create():

This looks similar to the issue discussed at:

  http://www.cygwin.com/ml/cygwin-patches/2006-q2/msg00065.html

As a workaround, it is currently possible to revert to version 1.5.18-1
of the "cygwin" package using the Cygwin Net Release Setup Program.

Since the probable cause of this issue has been identified and patched,
I will wait for a new release of the Cygwin DLL before investigating any
further.
