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. | ||
