##  MODULE
##
##      $RCSfile: dos-dj.mak,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 is the BibTeX makefile to build an MS-DOS 32-bit executable
##      using the DJGPP GNU C compiler. DJGPP V2 provides a clean DPMI
##	implementation. This file should be called "dos-dj.mak" and 
##      used with a command like:
##
##          [C:\] make -f dos-dj.mak bibtex
##
##      If you omit the "bibtex" argument, the Makefile will display list 
##      of the supported targets.
##
##      If you port BibTeX to a new environment or find that it works 
##      unchanged in a new environment, please report back to the author so 
##      that this file can be updated for everyone else.
##

##  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.

# Start of local definitions for file types and compilation / linking.  There
# are three small sections to customise:
#
#   BibTeX File Searching
#     - specifies the names of environment variables and paths to be used when
#       searching for input files
#
#   Utility Programs
#     - specifies the names of programs to be used for simple functions
#
#   Compiler/Linker
#     - specifies compiler/linker command lines
#
# If your system is already supported it should not be necessary to modify
# any part of the Makefile except these three sections.

#-----------------------------------------------------------------------------
# BIBTEX FILE SEARCHING
#
#   The macros in this section define the environment variables and default
#   search paths that will be used by BibTeX.  8-bit BibTeX looks for input
#   files in three different steps as summarised below.  As soon as 8-bit
#   BibTeX finds a matching file, it stops looking (i.e. only the first
#   matching file is used).  In order, the three steps are:
#
#     - look for the file in the current working directory.
#      
#     - if the appropriate environment variable has been set (e.g. BSTINPUT),
#       treat its value as a list of directories to be searched.  Look for the
#       file in each of the directories in the list.
#        
#     - if the appropriate environment variable (e.g. BSTINPUT) has not been
#       set, use a predefined "fallback" path as a list of directories to be
#       searched.
#
#   A search list consists of a number of directories separated by semicolons.
#
#   The following entries must be defined:
#
#     AUX_ENVVAR        the name of the environment variable defining the path
#                       to be searched for .aux files.
#
#     AUX_INPUT_PATH    the fallback path to be searched for .aux files.
#
#     BIB_ENVVAR        the name of the environment variable defining the path
#                       to be searched for .bib files (e.g. BIBINPUT).
#
#     BIB_INPUT_PATH    the fallback path to be searched for .bib files
#                       (e.g. e:/usr/latex/bibtex;e:/emtex/bibtex/bib).
#
#     BST_ENVVAR        the name of the environment variable defining the path
#                       to be searched for .bst files (e.g. BSTINPUT).
#
#     BST_INPUT_PATH    the fallback path to be searched for .bst files
#                       (e.g. e:/usr/latex/bibtex;e:/emtex/bibtex/bst).
#
#     CSF_ENVVAR        the name of the environment variable defining the path
#                       to be searched for .csf files (e.g. CSFINPUT).
#
#     CSF_INPUT_PATH    the fallback path to be searched for .csf files
#                       (e.g. e:/usr/latex/bibtex;e:/emtex/bibtex/csf).
#
#     CSF_FILE_ENVVAR   the name of the environment variable defining the
#                       fallback CS file (e.g. BIBTEX_CSFILE).
#
#     CSF_FILE_NAME     the name of the fallback CS file to be used if one is
#                       not specified on the command line and the above-named
#                       environment variable is not defined (e.g. cp850lat.csf).

# UTILITY PROGRAMS
#
#   MAKE                the command used to invoke Make to process this file.
#                       As distributed, it is defined as "make -f os2.mak"
#
#   RM	                rm program that won't complain (e.g. /bin/rm -f) if a
#                       file is missing
#-----------------------------------------------------------------------------
MAKE                = make -f os2.mak
RM                  = -DEL


#-----------------------------------------------------------------------------

# 
#   CC		        the command used to invoke the C compiler
#   CFLAGS	        compiler command line flags to be used

#   LDFLAGS	        linker command line flags to be used
#   LDLIBS	        linker command line option to search the specified
#		        library files

#                   -funsigned-char -c BIBTEX.C
#
#       -DMSDOS         we're building for MSDOS
#       -Wall           generate lots of warnings
#       -Wconversion    warn about suspicious type conversions
#       -Wno-char-subscripts    don't moan about character type subscripts
#       -funsigned-char unsigned chars
#       -c              compile only
#
#   Linking:    gcc BIBTEX.O BIBTEX-1.O -o BIBTEX.EXE
#
#       -o BIBTEX.EXE   produce executable BIBTEX.EXE
