# These symbols, when #defined using -D have these effects on compilation:
# ZMEM          - includes C language versions of memset(), memcpy(), and
#                 memcmp() (util.c).
# SYSV          - use <sys/dirent.h> and the library opendir()
# DIRENT        - use <sys/dirent.h> and getdents() instead of <sys/dir.h>
#                 and opendir(), etc. (fileio.c).
# NODIR         - used for 3B1, which has neither getdents() nor opendir().
# NDIR          - use "ndir.h" instead of <sys/dir.h> (fileio.c).
# UTIL          - select routines for utilities (note, cloak, and split).
# PROTO         - enable function prototypes.
# RMDIR         - remove directories using a system("rmdir ...") call.
# CONVEX        - for Convex make target.
# AIX           - for AIX make target.
# LINUX         - for linux make target.
