Yes.  And ugh.  One weekend when I had MS-DOS inflicted on me, I
started to write a glob routine that behaved sensibly.  (It just told
DOS to expand "*.*" in the appropriate directory and then filtered out
what it wanted on its own.)  It's not finished, but if enough people
are desperate enough to want it, I can probably dig out and post the
part that is finished.

There is nothing inherently difficult about this; my main problem was
that the machine I was on had no editor I would consider civilized.  I
was also using Microsoft's C compiler, that being what was available.
(Not my machine; I would never be happy on anything that small.)  The
version I was using (I think it was version 4.something, for what
that's worth) would bugcheck fairly easily, for example on the program

main()
{
 ((unsigned char far (*)[2])0xb0000000)[(0)+(80*(0))][0] = 0;
}

Yes, that mess resulted from a macro expansion, and yes, I was trying
to write to screen memory.  When either of the two (0) terms is
replaced by a variable such as (i) or (j), the bugcheck disappeared.
