It's probably someting simple, see config.log. Like I said, the patch is a
quick and dirty one and the AVR back end can use more work than that, most of
which means deleting patterns. Examples: All and, ior, xor, one_cmpl and sign
extend patterns larger than qimode, all zero_extend patterns, all movsi, movdi
and such. Along with that all the output_xxx functions in avr.c that they use.
