# Makefile for GNU Awk - ST version
#
# This is a subset of the full Makefile cut down for Atari ST
# gcc compiler is assumed
# It is known to work with gulam shell.
# It may need some customization depending on your setup!
# Replace with it 'Makefile' from the source directory.
#
# You need sed.ttp for an automatic creation of config.h file!
# Check gulam script mkconf.g in atari directory.
# In a pinch you may create one by checking config/atari file and
# editing config.h-dist by hand.
