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