/*****************************************************************************
* INSTRUCTIONS:
* =============
* The following should be handled in the Makefile:
* For USG Unix, define USG; for BSD Unix, don't (see ifdef USG).
* For 4.2 bsd, define V4_2BSD; this will replace the routines
* getwd() and rename() with the corresponding ones in the C-library.
* V4_2BSD also selects different definitions for the macros NCPFN and NCPPN
* (max. number of characters per filename, number of characters per path name).
* Define STRICT_LOCKING appropriately (see STRICT_LOCKING).
* The following need be changed for porting to a different machine:
* Define SMALLOG for a machine with small memory (like the PDP11).
* SMALLOG conserves space for log messages.
* Change BYTESIZ if necessary.
* If you need to change the comment leaders, update the table comtable[]
* in rcsfnms.c. (This can wait until you know what a comment leader is.)

/* $Log: rcsbase.h,v $
* Revision 4.9 89/05/01 15:17:14 narten
* botched previous USG fix
*
* Revision 4.8 89/05/01 14:53:05 narten

*
* Revision 4.7 88/11/08 15:58:45 narten

* Revision 4.6 88/08/09 19:12:36 eggert
* Shrink stdio code size; remove lint; permit -Dhshsize=nn.
*
* Revision 4.5 87/12/18 17:06:41 narten
* made removed BSD ifdef, now uses V4_2BSD
*
* Revision 4.4 87/10/18 10:29:49 narten

* Changes relative to 1.1 are actually relative to 4.2
*
* Revision 1.3 87/09/24 14:02:25 narten

* Initial revision
*
* Revision 4.2 83/12/20 16:04:20 wft
* merged 3.6.1.1 and 4.1 (SMALLOG, logsize).
* moved setting of STRICT_LOCKING to Makefile.
* changed DOLLAR to UNKN (conflict with KDELIM).
*
* Revision 4.1 83/05/04 09:12:41 wft
* Added markers Id and RCSfile.
* Added Dbranch for default branches.
*
* Revision 3.6.1.1 83/12/02 21:56:22 wft

*
* Revision 3.6 83/01/15 16:43:28 wft
* 4.2 prerelease
*
* Revision 3.6 83/01/15 16:43:28 wft
* Replaced dbm.h with BYTESIZ, fixed definition of rindex().
* Added variants of NCPFN and NCPPN for bsd 4.2, selected by defining V4_2BSD.
* Added macro DELNUMFORM to have uniform format for printing delta text nodes.
* Added macro DELETE to mark deleted deltas.
*
* Revision 3.5 82/12/10 12:16:56 wft
* Added two forms of DATEFORM, one using %02d, the other %.2d.
*
* Revision 3.4 82/12/04 20:01:25 wft
* added LOCKER, Locker, and USG (redefinition of rindex).
*
* Revision 3.3 82/12/03 12:22:04 wft
* Added dbm.h, stdio.h, RCSBASE, RCSSEP, RCSSUF, WORKMODE, TMPFILE3,

* using NCPPN. Changed putc() to abort on write error.
*
* Revision 3.2 82/10/18 15:03:52 wft
* added macro STRICT_LOCKING, removed RCSUMASK.
* renamed JOINFILE[1,2] to JOINFIL[1,2].
