cygwin.dll is covered by the GPL and they try fairly hard to enforce
that in its entirety.  In this case it should not be a problem, but the
2 main issues are:

1) All code that calls cygwin.dll must also be gpl.  (rdiff-backup
qualifies.)
2) The source code for cygwin.dll must be made available to end-users
(for 5 years??) by anyone distributing cygwin.dll.

The source code issue seems to be the one people try to ignore.

The cygwin team does NOT consider a simple pointer to their website as
satisfying this requirement.  They claim the simplist way to satisfy the
GPL license is to simply distribute the source to cygwin.dll with your
application.  Otherwise you have to ensure you have the cygwin source
available for 5 years (IIRC).
