I understand that this code resides in the RTL, which I would need to
re-implement for the "embedded" system anyway. Here I simply could
disable/enable interrupt to disallow a task switch.
Yes, they reside in $fpc/m68k/m68k.inc and are normally OS independant
as they normally use corresponding CPU instructions. There are
exceptions though like the kuser_xchg, etc functions provided on certain
arm-linux systems.
