** MODULE
**
** $RCSfile: sysdep.h,v $
** $Revision: 3.71 $
** $Date: 1996/08/18 20:37:06 $
**
** DESCRIPTION
**
** A 32-bit implementation of BibTeX v0.99c for MS-DOS, OS/2 2.x,
** Unix and VMS. This C language implementation is based on the
** original WEB source but it has been enhanced to support 8-bit input
** characters and a very large processing capacity.
**
** For documentation describing how to use and build this program,
** see the 00README.TXT file that accompanies this distribution.
**
** MODULE CONTENTS
**
** This module defines as many system dependent things as possible.
** System / compiler dependent code should only appear in sysdep.h,
** bibtex.c and utils.c. System dependent code should be delimited by
** preprocessor conditionals. Look for:
**
** #ifdef MSDOS
** #ifdef OS2
** #ifdef UNIX
** #ifdef VMS
**
** AUTHORS
**
** Original WEB translation to C, conversion to "big" (32-bit) capacity,
** addition of run-time selectable capacity and 8-bit support extensions
** by:

** Niel Kempson
** Snowy Owl Systems Limited, Cheltenham, England
** E-mail: kempson@snowyowl.co.uk
**
** 8-bit support extensions also by:

** Universidad Nacional Aut\'onoma de M\'exico, M\'exico

**
** ACKNOWLEDGEMENT
**
** The original BibTeX was written by Oren Patashnik using Donald
** Knuth's WEB system. This format produces a PASCAL program for
** execution and a TeX documented version of the source code. This
** program started as a (manual) translation of the WEB source into C.
**
** CHANGE LOG
**
** $Log: sysdep.h,v $
** Revision 3.71 1996/08/18 20:37:06 kempson
** Official release 3.71 (see HISTORY file for details).
**
** Revision 3.70 1996/04/08 10:08:40 kempson
** Final documentation & cosmetic changes for official release 3.70.
**
** Revision 3.6 1995/10/21 22:13:13 kempson
** Added support for DJGPP under MSDOS.
**
** Revision 3.5 1995/09/24 20:44:37 kempson
** Many changes for final beta test version.
**
** Revision 3.4 1995/04/09 22:15:46 kempson
