   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.
