Nope, that’s MMU-less (IIRC).

I’ve had contact with him recently, and he’s very interested in
other m68k-related work.

Maybe you didn’t know something else? ;-)
mksh (other than crippled shells such as ash) is, for example, the
only one with system dependencies low enough to run unmodified on
Android bionic (even going as far back as Android 1.5, which was
the first one I had contact with). It is also much faster than GNU
bash and (obviously) more free ☺
But the thing is, building mksh and running its testsuite has a
history of exposing compiler, toolchain or OS bugs. So you get
double benefit.

That may be a bug in the operating system. I’ve read about it,
thanks to RT who ported mksh to NeXTstep, and the thing is, if
you use a sequence like this:
echo foo >file
echo bar >>file
… to create a file, and the *first* echo is less than 14 bytes,
the file gets corrupted. (Look in mksh/Build.sh for “workaround”.)

;-) I can confirm that it’s possible to build at least gcc-4.4 straight
from gcc-3.4.6 since the latter is the system compiler on MirBSD (will
be replaced with pcc eventually though) and the former is in MirPorts.
Although I did collect a number of patches against 3.4… (but that’s on
i386 and sparc, which are MirBSD’s currently supported platforms).

Thanks, will peek at it.

Isn’t it for all of us? I learned to know Debian by reviving m68k…
even though I’ve been a programmer since approximately when I was
six years old. (Games were few and held few interest for me when
I had GWBASIC to toy with the computer with.) You never stop learning.

FWIW, I'm quite impressed with mksh interactively. I thought it was much
*much* more bare bones. But it turns out it beats the living hell out of
ksh93 in that respect. I'd even consider it for my daily use if I hadn't
wasted half my life on my zsh setup. :-) -- Frank Terbeck in #!/bin/mksh
