For anything arm-embedded, it would probably be a better idea to use the 
latest SVN version. Simply because arm-embedded is a much less used and 
tested branch, the functionality might be slower to get into releases. 
In SVN trunk the distinction between Cortex-M3 and ARMv7M is removed and 
everything has been changed to ARMv7M. This is why the wiki page only 
mentions ARMv7M.

No, fpc should be trying to call ppcrossarm(since you are 
crosscompiling, I guess. I suppose you don't work on an ARM host). I 
don't know why it doesn't do that in your case, might be related to the 
way it was originally built for your platform.
