+* Wed Feb 23 2011 Fabio M. Di Nitto <fdinitto@redhat.com>
+- enable build on sparcv9
+- add ghc-fix-linking-on-sparc.patch to fix ld being called
+  at the same time with --relax and -r. The two options conflict
+  on sparc.
+- bump BuildRequires on ghc-rpm-macros to >= 0.11.10 that guarantees
+  a correct build on secondary architectures.
