+* Wed Jan 25 2012 Petr Machata <pmachata@redhat.com> - 1.48.0-9
+- Only build the long double math libraries on arches that support
+  long double.
+- ARM was considered unsupporting, because libc defines
+  __NO_LONG_DOUBLE_MATH.  Ignore this setting, ARM has perfectly
+  working long double that just happens to be only as long as double.
+- Resolves: #783660
+
 * Mon Jan 16 2012 Petr Machata <pmachata@redhat.com> - 1.48.0-8
 - Add underscores around several uses of __attribute__((X)) to prevent
   interactions with user-defined macro X
