      4 # By default, flex will be configured to generate 8-bit scanners only if the
      5 # -8 flag is given.  If you want it to always generate 8-bit scanners, add
      6 # "-DDEFAULT_CSIZE=256" to CPPFLAGS.  Note that doing so will double the size
      7 # of all uncompressed scanners.
      8 # 
      9 # If on your system you have trouble building flex due to 8-bit character
     10 # problems, remove the -8 from FLEX_FLAGS and the "#define FLEX_8_BIT_CHARS"
     11 # from the beginning of flexdef.h.
     12 #
     13 # To bootstrap lex, cp initscan.c to scan.c and run make.
