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