I've written few words here about symlink support.

Any comments?

 @cindex Symlinks, emulation
 DOS doesn't support hard and symbolic links.  However, @sc{djgpp}
 emulates them to some extent.  The @code{link} library function
-simulates hard links by copying.  The @code{symlink} library function
-simulates a symbolic link for executable programs only, by creating a
-2KB stub which is set up to run the COFF image from the target of the
-link.  Thus, @samp{ln -s grep fgrep} does what you'd expect.
+simulates hard links by copying.  Symbolic links are fully emulated by most 
+file handling functions in the library.  Also, symlink support API you would 
+expect find only on UNIX (such as @code{readlink}) is present. Function 
+@code{symlink} creates files with special size and format which are 
+transparently to user recognized by other library functions.  Because DOS 
+itself and most DOS applications weren't designed with symlinks in mind, there
+is a subset of file handling API which intentionally does not support symlinks.
+This includes functions with @code{_dos_} prefix, as well as other functions
+with DOS origin, such as @code{findfirst}.
