Subject: Unix Tools ...

If you're interested in Unix tools, there is a fairly complete port
done [a long time ago in computer development time] by Eric Backus on
//ftp.math.niu.edu/pub/msdos/djgpp.stuff or some such.  (The host is
right, the path is right or almost so.)  However, they are "old", and
I suspect that recent DJGPP compilers will compile much more easily.
    But *beware*:

RECENT DJGPP LIBRARY IMPLEMENTATIONS "STUB" MOST INTRACTABLE UNIX
FUNCTIONS such as pipe(), fork(), vfork(), and so on.  These will
return with error messages (or stack dumps in the case of pipe()).
The reason for the stack dump is that many programs (I'm thinking of
Imake from X Windows, and possibly Ghostscript's Unix code) don't use
strerror(), and don't check to be sure that the string description is
present in the error message table.  This often results in an illegal
pointer, and a stack dump.
