  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.
