ACK ANSI C Compiler

[Chad <chad.page@gmail.com>]

I've downloaded and compiled ACK, which took about 4.5minutes on my
p-m notebook - been looking for something like the 'em' targets for a
few days now.  Very nice, and I'm glad it's BSD licensed, too.

Getting ELKS user space apps working will mostly be a library issue -
the convertor shouldn't be a big deal.  In fact, 'file' thinks a.out
is a Linux-8086 executable already.  It looks like we can either port
the bin86 libc or adapt included (minix?) libc to make ELKS system
calls.

Given the way ack works we might have real trouble with the kernel's
inline assembly - we'll have to move as much of the embedded assembly
as possible into assembly files, and make the ack linker deal with
them.  I'd have to look at the minix code to see how things are dealt
with there.

OBCrazyTalk: With particularly twisted hacks of em, and a multi-task
interpreter, and some *really* tight and small code, something
ELKSlike might, just might run on a Z80... ;)  It would certainly run
under regular Linux as a process, though.
