well, just compiler will complain... but if you do not mind... ~d P.S. if you'll not specify mcu arch, the gcc will not generate hardware multiplication code and probably will link wrong library. Also, it might be possible that start address/stack top will be set 'unefficiently'. I think this is easier to say -mmcu=msp430x449 than define arch in sources, specify stack/etc. addresses and provide a linker script. But if you find this easier... :)
