Not at all, but I would start looking at http://www.mobile-stream.com/devzone.html . Either way and since it seems that requires the propietary, Win32 only "pacc.exe" compiler, I believe the best way to do arm so's is to just use a "PNO Loader on steroids" like peal, which can also act as a dynamic linker (it is in fact a bare-bones elf linker). The linker itself being 68k code means you could call any PNO function from any 68k code.
