This is a "sneak preview" port of GCC 4.3.1 for the Atmel AVR
microcontrollers. It includes patches from the WinAVR project to
support the ATmega32C1, ATmega32M1, ATmega32U4, and ATtiny167
controllers, and in particular the next generation AVRs ATxmega64A1
The port has been carefully crafted to peacefully coexist with the
non-devel avr-gcc port. All executables installed have the suffix
"-43" added for that reason.
