   7:  * INSTRUCTIONS:
   8:  * =============
   9:  * For USG Unix, define USG; for BSD Unix, don't (see ifdef USG).
  10:  * For 4.2 bsd, define V4_2BSD; this will replace the routines
  11:  * getwd() and rename() with the corresponding ones in the C-library.
  12:  * V4_2BSD also selects different definitions for the macros NCPFN and NCPPN
  13:  * (max. number of characters per filename, number of characters per path name).
  14:  * Define STRICT_LOCKING appropriately (see STRICT_LOCKING).
  15:  * Change BYTESIZ if necessary.

  32:  * Make teeny logsize big
  33:  *
  34:  * Revision 3.6  83/01/15  16:43:28  wft
  35:  * 4.2 prerelease
  36:  *
  37:  * Revision 3.6  83/01/15  16:43:28  wft
  38:  * Replaced dbm.h with BYTESIZ, fixed definition of rindex().
  39:  * Added variants of NCPFN and NCPPN for bsd 4.2, selected by defining V4_2BSD.
  40:  * Added macro DELNUMFORM to have uniform format for printing delta text nodes.
  41:  * Added macro DELETE to mark deleted deltas.
  42:  *
  43:  * Revision 3.5  82/12/10  12:16:56  wft
  44:  * Added two forms of DATEFORM, one using %02d, the other %.2d.
  45:  *
  46:  * Revision 3.4  82/12/04  20:01:25  wft
  47:  * added LOCKER, Locker, and USG (redefinition of rindex).
  48:  *
  49:  * Revision 3.3  82/12/03  12:22:04  wft
  50:  * Added dbm.h, stdio.h, RCSBASE, RCSSEP, RCSSUF, WORKMODE, TMPFILE3,
  51:  * PRINTDATE, PRINTTIME, map, and ctab; removed Suffix. Redefined keyvallength
  52:  * using NCPPN. Changed putc() to abort on write error.
  53:  *
  54:  * Revision 3.2  82/10/18  15:03:52  wft
  55:  * added macro STRICT_LOCKING, removed RCSUMASK.
  56:  * renamed JOINFILE[1,2] to JOINFIL[1,2].
  57:  *
  58:  * Revision 3.1  82/10/11  19:41:17  wft
  59:  * removed NBPW, NBPC, NCPW.
  60:  * added typdef int void to aid compiling
