Very Computer

I recently installed Slackware 3.1 (3.0? - Sept '96) onto my machine at work.
Install went fine. Then I tried to compile the latest dosemu (0.64.3).

I have ftp'ed 2.0.28 kernel sources, installed and compiled (and am running)
the 2.0.28 kernel. I've installed XFree86 3.2A, etc, so things appear to be
working correctly. However, when I try to compile dosemu, I get the
following errors (see [COMMENT] below)

make[3]: Entering directory `/usr/src/dosemu-0.64.3/src/tools/periph'

/usr/include/unistd.h:630: parse error before `__increment'

[COMMENT] This line reads (from memory) something like:
function modifiers ( (ptrdiff_t __increment) );

ptrdiff_t IS define in malloc.h, which is NOT included by default in
unistd.h. This makes me think either the header file is broken, or there's
some other setup problem.. If I edit unistd.h to #include malloc.h, it gets
as far as line 656 below. At that point, I can't find a defintion of
"dev_t" ANYWHERE, which is really bizzare, as it's also used by the kernel
sources (/usr/src/linux/fs/namei.h). However, my kernel recompiled fine (at
least when I first installed everything). Have I inadvertently
corrupted/erased something? Or is dosemu not quite kosher?

(note: it also mentions stdin on the line above, but I can't remember
exactly where)

In a larger program, it complains about each of the included header files.
Then, it gives a parse error, and then exhausts virtual memory.

The question is, what have I messed up? I originally installed 2.7.2 and
have just installed 2.7.2.1 overtop of it.

Any clues? I'm not above re-installing all of gcc. What's the easiest way to
install a brand new 2.7.2.1 setup? I've already ftp'ed half the files I'm
sure, so it shouldn't be that hard..

Email preferred, but as long as you don't take the thread out of
comp.os.linux.setup, I'll follow it there too

Thanks,
