[Debian-med-packaging] Bug#560933: Expat issues update

[Michael Gilbert]

Hi all,

In order to guarantee that the system expat is used, the
'--with-expat=sys' configure argument must be used.  If you think
your package is already using the system expat, or if you are updating
your package to use the system expat, please check to make sure that
this option is being used. Thanks.

Mike
