Aren't those areas conditioned on something like "#ifdef S_ISLNK"?  If
they aren't, you should report this as a bug to the maintainer(s) of
MC (there are some old versions of Unix that don't support symlinks as
well, and Posix doesn't require it).

S_ISLNK shoud be left undefined, and the source should test for 
#ifdef S_ISLNK.  This *is* the standard method (see, e.g., the sources
if GNU Fileutils).
