+From: Pino Toscano <pino@kde.org>
+Subject: Fix platform file for GNU/Hurd
+ Currently (both in cmake 2.6.x and cmake 2.8 as of its latest rc5), the
+ GNU.cmake platform file used for GNU/Hurd systems is not complete.  In
+ particular, it needs the rpath-link flag definition, needed for properly
+ compiling in all the cmake setups; in particular, its miss causes the failure
+ of the ExportImport unit test, which instead works correctly with the proposed
+ patch.  Also, the patch provides some more definitions, a bit close to the
+ Linux oones (given the base toolchain is quite close anyway, GNU-based).
