* Also, get rid of the WIN16 code, do other cleanup.

* Revision 6.2  1998/06/25 19:39:18  vakatov
* Added "FileLengthEx()" -- it returns -1(not 0!) if the file does not exist
*
* Revision 6.1  1998/05/24 19:20:58  kans
* added Nlm_DirCatalog (Mac implementation only so far)
*
* Revision 5.1  1996/12/03 21:48:33  vakatov
