+# 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.

+Vern,
+
+I've made flex 2.5.0.6 successfully with no changes to the source
+code at all.  I'm including the Borland 4.02 makefile and config.h
+at the end of this message.
+
+When you're ready for release, I'll be happy to take care of getting
+the appropriate archive files up to Simtel if you wish.
+
+I have not used this version for any of my "work-related" scanners
+yet, but have run the fastwc benchmark.  The compiles were for large
+memory model and optimization for fastest possible code.  The test
+machine was a Pentium-90 (hey! timing output was integer!) with
+enhanced IDE on a PCI bus and no file system caching.  I ran the
+test on two different input files.
+
+(Times are in seconds.)
+
+The first input was a typical postscript file concatenated 10 times;
+by typical, I mean that there were relatively few spaces, lots of lines
+with no space, using lots of parentheses.

+The second test run was on a file that consisted of 20 concatenations
+of 'misc/flex.man'.
