I've noticed a variation of this issue, where there is a check for the 68000 with __mc68000__ or mc68000 and there will be "false positives" when compiling for the 68020 and above: https://github.com/freemint/freemint/blob/76262f82c1594aa0c59ee72803824924daf6026c/sys/libkern/unaligned.c#L35 https://github.com/freemint/freemint/blob/76262f82c1594aa0c59ee72803824924daf6026c/sys/libkern/asm/quickmove.S#L49 https://github.com/freemint/freemint/blob/76262f82c1594aa0c59ee72803824924daf6026c/tools/crypto/crypt.c#L135 |
