# To incorporate the 7300/3b1 shared library, run this script in place
# of 'CC'.
# You can skip this is you have the shcc program installed as cc in
# your path.
# First: Run 'Configure' through to the end and run 'make depend'.
# Second: Edit 'makefile' ( not Makefile ) and set CC = 3b1cc.
# Third: Edit 'x2p/makefile' and set CC = 3b1cc.
#
# Do not use '3b1cc' as the default compiler.  The call to the default
# compiler is used by 'perl' and will not be available when running
# 'perl'.
#
# Note: This script omits libraries which are redundant in the shared
# library.  It is an excerpt from a grander version available upon
# request from "zebra!vern" or "[email protected]".
