# These symbols, when #defined using -D have these effects on compilation:
# ZMEM                  - includes C language versions of memset(), memcpy(),
#                         and memcmp() (util.c).
# HAVE_DIRENT_H         - use <dirent.h> instead of <sys/dir.h>
# NODIR                 - for 3B1, which has neither getdents() nor opendir().
# HAVE_NDIR_H           - use <ndir.h> (unix/unix.c).
# HAVE_SYS_DIR_H        - use <sys/dir.h>
# HAVE_SYS_NDIR_H       - use <sys/ndir.h>
# UTIL                  - select routines for utilities (note, cloak, split)
# NO_RMDIR              - remove directories using a system("rmdir ...") call.
# NO_PROTO              - cannot handle ANSI prototypes
# NO_CONST              - cannot handle ANSI const
