+Subject: [PATCH 1/2] replace abs() with std::abs() for gcc6 compatibility
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Building with GCC 6 fails with "call of overloaded ‘abs(double)’ is
+ambiguous" - for some reason only on PowerPC and PPC64.

+Subject: [PATCH 2/2] Fix FTBFS for glibmm Glib::RefPtr
+
+Now we can use operator RefPtr::operator bool() to test if it is NULL.
+RefPtr::operator== can not work on int.
