- * The follow should be set to reflect the type of system you have:
- * JOBS -> 1 if you have Berkeley job control, 0 otherwise.
- * SYMLINKS -> 1 if your system includes symbolic links, 0 otherwise.
- * DIRENT -> 1 if your system has the SVR3 directory(3X) routines.
- * UDIR -> 1 if you want the shell to simulate the /u directory.
- * ATTY -> 1 to include code for atty(1).
- * SHORTNAMES -> 1 if your linker cannot handle long names.
- * define BSD if you are running 4.2 BSD or later.
- * define SYSV if you are running under System V.
- * define DEBUG=1 to compile in debugging (set global "debug" to turn on)
- * define DEBUG=2 to compile in and turn on debugging.
- *
- * When debugging is on, debugging info will be written to $HOME/trace and
- * a quit signal will generate a core dump.
