3# By default, flex will be configured to generate 8-bit scanners only if the
4# -8 flag is given.  If you want it to always generate 8-bit scanners, add
5# "-DDEFAULT_CSIZE=256" to CFLAGS.  Note that doing so will double the size
6# of all uncompressed scanners.
7#
8# Bootstrapping of lex is handled automatically.
9# Also note that flex.skel no longer gets installed.
