Additionally I want to add, that new ATARI ST software (or old one where Source code is available) can be compiled with new version of gcc and GFA-Basic compiler in Coldfire native code, that is quite optimized and has very optimal results. (at least this version of gcc should also be usefull on Amiga and Mac68K platform)

I was surfing back thorough this thread and this statement seems to infer that GFA-Basic itself is CF native and/or can produce CF native binaries. This is false. GFA-Basic and all related tools are not CF native, nor can it generate CF native binaries. It was fixed to co-exist with CF68kLib included in FireTOS. Please fact check before posting. ;)

There is a new version of GFA basic which is CF native.

Walk through here: EXTERNAL LINK

The link you provided never states GFABASIC is Coldfire native. It says compatible. There's a huge difference between compatible and native when it comes to the FireBee. As the current maintainer of GFABASIC I should know. You clearly do not understand how it works.

Please research CF68KLib!
