/*
* The follow should be set to reflect the type of system you have:
* DOS_PATHS -> 1 if you are working on a DOS filesystem
* 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.
