JFYI __builtin_avr_fmul(), __builtin_avr_fmuls(), __builtin_avr_fmulsu() don't 
work for me (they produce internal compiler errors). I looked into the patch 
some time ago and found out that IMHO line 576 should be 
+  for (i = 0, d = bdesc_2arg; i < ARRAY_SIZE (bdesc_2arg); i++, d++)
instead of
+  for (i = 0, d = bdesc_1arg; i < ARRAY_SIZE (bdesc_2arg); i++, d++)

But there seems to be another problem, the functions still didn't work (the 
compiler complained about an unknown insn or sth. like that IIRC). I didn't 
have the time to look deeper into that.
