The CodeSourcery GCC builds have supported CM3 since it came out. And now
Cortex-M1. Debug differs from ARM7/9 so you'll need to investigate
appropriate tools there.

Well, there's a Cortex-M3 Y! group, and I'm not sure how the people in it
dress. I don't dress smart, jeans and a T-shirt every days.

Only 62 members though... STM32 is causing a stir. NXP are on the CM3
bandwagon too.
