Not sure why you were trying to use Windows. Linux is the way to go at the moment. Native GCC for Native AROS is being worked on. I think it's close. Then it will be possible to use AROS to develope for AROS.
The 68K version of AROS has been abandoned by it's maintainer and noone has been found to pick it up.
You might want to check out the AROS Development Forum here or the forums at
AROS-EXEC.
