# Makefile for flex 2.4.7 for the Amiga using SAS/C 6.51
# 08/17/94 by Carsten Steger <stegerc@informatik.tu-muenchen.de>
#
# If you build flex from scratch, you will have to call smake twice because
# of a bug in smake that tries to generate scan.c by using flex, although
# the rule for .bootstrap has already copied initscan.c to scan.c.
