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. |
