-* Tue Jul  9 2013 Tim Waugh <twaugh@redhat.com> 9.07-8.1
-- Test build for debugging bug #979681.  WRF_wfloat() now aborts if
-  the buffer would have been truncated.
+* Wed Jul 17 2013 Tim Waugh <twaugh@redhat.com> 9.07-10
+- Added in missing part of gs_sprintf backport: add in the header to
+  stdio_.h. Without this there are problems with va_args on some
+  platforms (bug #979681).
