+* Thu Apr 10 2008 Adam Jackson <ajax@redhat.com> 7.1-0.23
+- mesa-7.1-link-shared.patch: Make a libdricore.so from libmesa.a, install
+  it into %%_libdir/dri, and link the DRI drivers against it.  Drops ~20M
+  from the installed system (not including debuginfo).  Inspired by a
+  similar patch in openSUSE but reworked to be compatible with the OSMesa
+  build.
+
 * Wed Apr 09 2008 Adam Jackson <ajax@redhat.com> 7.1-0.22
 - mesa-7.1-visual-crash.patch: Fix a segfault if DRI unavailable.
 - mesa-7.1-fbconfig-fix.patch: Fix fbconfig comparisons.
