Hi, applied this obvious patch to trunk in order to fix build warnings like these:

gcc/config/avr/avr-fixed.md:434:59: warning: narrowing conversion of ‘-1’ from 
‘int’ to ‘const unsigned int’ inside { } is ill-formed in C++11 [-Wnarrowing]


Thanks, Johann


gcc/
	* config/avr/avr-fixed.md (round<mode>3): Use -1U instead of -1 in
	unsigned int initializers for regno_in, regno_out.
