# Notes on building:

# Possible values for DEFS:
#
# By default, flex generates 8-bit scanners when using table compression,
# and 7-bit scanners when using uncompressed tables (-f or -F options).
# For flex to always generate 8-bit scanners, add "-DDEFAULT_CSIZE=256"
# to DEFS.
#
# For Vax/VMS, add "-DVMS" to DEFS.
#
# For MS-DOS, add "-DMS_DOS" to DEFS.  See the directory MISC/MSDOS for
# additional info.
