Hello.  I've been trying to compile the new BSD-style ls on MINIX/PC.  It
compiles fine, and "ls -CF" works for all directories up to a certain size.
However, for some of the bigger directories, it just lists nothing.  If I type
"ls -CF *" in the same directory, it works.

I've tracked the problem down to a buffer overflow in getdents().  I've also
found that if I change a constant (DIRBUF, I think) in some header file
(dirent.h, I think), to more than the size listed for the large directory
(8192 bytes to be safe, I think) and recompile, then everything works fine.
I get the feeling, though, that this is not the right way to fix the problem.

Does anyone know what's going on?  Suggestions for a proper fix?

	Thanks in advance,
		Jerry
