In addition to using ln.exe built with CVS libc, as Martin said, you
should test this with files that are not programs.  Functions such as
open, opendir, remove, rename, etc. should DTRT with symlinks.

Compiling and linking a bunch of files in a directory that is a
symlink might test quite a few of these functions.  In fact, you could
try making the DJGPP installation directory be a symlink, and see if
anything breaks, but that requires that you rebuild _everything_ with
CVS libc.

Note that invoking programs that are symlinks (in the v2.04 sense of
that) will only work from a DJGPP program compiled with CVS libc.
DOS, of course, knows nothing about symlinks.
