O_NDELAY, O_CLOEXEC, F_SETFL, F_DUPFD etc
* Address validation checks on all syscall copies
* Builds with a modern ANSI C compiler (SDCC)
-* Kernel boots to userspace on both 6502 (bitrotted), 65C816, 68000, 6809, MSP430 and Z80/Z180
-* Core code can be built for 6502, 65C816, 6809, 68HC11, 68000, 8086, MSP430, pdp11 and Z80/Z180 so should
