#	@(#)Makefile	1.2 (2.11BSD GTE) 1996/3/26
#
# This is the Makefile for 'libkern.a'.  These are the specially compiled
# versions of libc.a routines which the kernel and network use.
#
# There are no source files in this directory.  Links are made to the files.
#
# libkern.a needs to be installed only once (usually when the 
# C library is installed) rather than compiling the sources each time 
# a kernel is compiled..
