These patches fix two bugs:
"\^" not correctly matching a caret
flex scanners compiled using -f or -F can die
#! /bin/sh
# This is a shell archive. Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file". To overwrite existing
# files, type "sh file -c". You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g.. If this archive is complete, you
# will see the following message at the end:
# "End of shell archive."

if test -f 'patch.1' -a "${1}" != "-c" ; then
echo shar: Will not clobber existing file \"'patch.1'\"
else

sed "s/^X//" >'patch.1' <<'END_OF_FILE'
Greg Lee mentioned a bug regarding "\^" not correctly matching a caret
in the input. This is due to a throw-back to the dark ages, and the
fix follows.
