Details:
The compiler exits with the msg "Error: illegal opcode mul for mcu
at90usb162", when I run the following command:
$avr-gcc -mmcu=at90usb162 -Os -Wa,-adhlms=bugrprt.lst bugrprt.c -o
bugrprt.o
The sample C code is attached. Using -O0 it compiles ok.

version.h
#define __AVR_LIBC_VERSION__ 10407UL
$avr-gcc -v
