# Partial makefile common to all Unix configurations.

# This is the last part of the makefile for Unix configurations.
# Since Unix make doesn't have an 'include' facility, we concatenate
# the various parts of the makefile together by brute force (in tar_cat).

# Define the name of this makefile.
UNIXTAIL_MAK=unixtail.mak

# The following prevents GNU make from constructing argument lists that
# include all environment variables, which can easily be longer than
# brain-damaged system V allows.
