Subject: patches and makefile for Borland C 4.02, flex 2.4.7
To: vern@ee.lbl.gov
Date: Thu, 29 Sep 1994 10:26:42 -0400 (EDT)
X-Mailer: ELM [version 2.4 PL23]
Mime-Version: 1.0
Content-Type: text/plain; charset=US-ASCII
Content-Transfer-Encoding: 7bit
Content-Length: 9900
Enclosed are unified diffs and a makefile for Borland 4.02
The changes in the enclosed are 1) make the size parameters for memory
allocation "size_t", 2) change an include file when the lexer is
compiled within 'extern "C" {...}' in a C++ file, and 3) include pragmas
in the header suitable for BCC 4.02 to hush on warnings.
The latter is done because of the limit on command line size. A tradeoff
exists between putting pragmas in the header, or #defines in the header -
I put in the pragmas since they're suppoed to be ignored unless
understood - *and* they're enclosed in BCC specific ifdefs, anyway.
All changes are enclosed in "#ifdef __BORLANDC__".

# Makefile for flex 2.4.7 with Borland C/C++ version 4.02
#
# This will probably need to be adjusted for your existing lexer/parser
# generators. See definitions for FLEX and YACC near the bottom of the
# makefile.
#
# Copy initscan.c to scan.c to make your first executable. After that,
# you may choose to try alternate compression options for your everyday
# flex executable.
#
# This will build flex with the large model. Don't use huge, but if you
# feel like experimenting with other models, post your success stories to
# comp.compilers, OK?
#
# This makefile does *not* implement the big testing found in "makefile.in".
#
# I also assume the availability of sed and the gnu file utilities on the
# system - they're readily available, so if you don't have them, why not?
#
#
# The resulting generated lexer (the real goal, right?) will compile
# (and run nicely, too) as a .c file, as well as being included such as
# extern "C" { #include "lexyyc" } in a .cplusplus file.
