+<p>On AVR, support has been removed for the command line
+  option <code>-mshort-calls</code> deprecated in GCC 4.7.</p>

+<p>On AVR, the configure option <code>--with-avrlibc</code> supported since
+  GCC 4.7.2 is turned on per default for all non-RTEMS configurations.

+  <a href="http://www.nongnu.org/avr-libc/">AVR Libc</a> with avr-gcc.
+  For technical details, see <a href="http://gcc.gnu.org/PR54461">PR54461</a>.
+  To turn off the option in non-RTEMS configurations, use
+  <code>--with-avrlibc=no</code>.  If the compiler is configured for
+  RTEMS, the option is always turned off.</p>
