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 | * DIRENT -> 1 if your system has the SVR3 directory(3X) routines. | |
44 | * UDIR -> 1 if you want the shell to simulate the /u directory. | |
45 | * ATTY -> 1 to include code for atty(1). | |
46 | * SHORTNAMES -> 1 if your linker cannot handle long names. | |
47 | * define BSD if you are running 4.2 BSD or later. | |
48 | * define SYSV if you are running under System V. | |
49 | * define DEBUG=1 to compile in debugging (set global "debug" to turn on) | |
50 | * define DEBUG=2 to compile in and turn on debugging. | |
51 | * | |
52 | * When debugging is on, debugging info will be written to $HOME/trace and | |
53 | * a quit signal will generate a core dump. | |
