The Clause:
In accordance with section 10 of the GPL, Red Hat permits programs whose
sources are distributed under a license that complies with the Open Source
definition to be linked with libcygwin.a/cygwin1.dll without
libcygwin.a/cygwin1.dll itself causing the resulting program to be covered
by the GNU GPL.

the problem: The OSF was unable to decide if the BSDPL is OSD complient. It
looks like they may have concluded it was not. See the thread at
http://www.mail-archive.com/license-discuss@opensource.org/msg04670.html

No discussion was held on debian-legal about this licence and its DFSG
freeness, AFIACT.
