/* Since older versions of the Lattice C compiler for Amiga, and all current */
/* versions of the Manx Aztec C compiler for Amiga, either provide no stat() */
/* function or provide one inadequate for unzip (Aztec's has no st_mode      */
/* field), we provide our own stat() function in stat.c by Paul Wells, and   */
/* this fake stat.h file by Paul Kienitz.  Paul Wells originally used the    */
/* Lattice stat.h but that does not work for Aztec and is not distributable  */
/* with this package, so I made a separate one.  This has to be pulled into  */
/* unzip.h when compiling an Amiga version, as "amiga/z-stat.h".             */

/* We also provide here a "struct direct" for use with opendir() & readdir() */
/* functions included in amiga/stat.c.  If you use amiga/stat.c, this must   */
/* be included wherever you use either readdir() or stat().                  */

/* This include file should ONLY be loaded if AZTEC_C is defined, and
 * you are using the substitute version of stat() from amiga/stat.c.
 * Bit definitions are based on those in headers for SAS/C v6.0
