40 * The follow should be set to reflect the type of system you have:
41 *	JOBS -> 1 if you have Berkeley job control, 0 otherwise.
42 *	SYMLINKS -> 1 if your system includes symbolic links, 0 otherwise.
43 *	SHORTNAMES -> 1 if your linker cannot handle long names.
44 *	define BSD if you are running 4.2 BSD or later.
45 *	define SYSV if you are running under System V.
46 *	define DEBUG=1 to compile in debugging (set global "debug" to turn on)
47 *	define DEBUG=2 to compile in and turn on debugging.
48 *
49 * When debugging is on, debugging info will be written to $HOME/trace and
50 * a quit signal will generate a core dump.
