42  * The follow should be set to reflect the type of system you have:
43  *	JOBS -> 1 if you have Berkeley job control, 0 otherwise.
44  *	SHORTNAMES -> 1 if your linker cannot handle long names.
45  *	define BSD if you are running 4.2 BSD or later.
46  *	define SYSV if you are running under System V.
47  *	define DEBUG=1 to compile in debugging (set global "debug" to turn on)
48  *	define DEBUG=2 to compile in and turn on debugging.
49  *	define DO_SHAREDVFORK to indicate that vfork(2) shares its address
50  *	       with its parent.
51  *
52  * When debugging is on, debugging info will be written to $HOME/trace and
53  * a quit signal will generate a core dump.
