# Makefile for flex 2.5.0.6 (beta) 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.
#
# This makefile builds initflex.exe and flex.exe by default. It
# removes initflex.exe after making flex.exe. 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?
# <grin>
#
# 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.
