makefile

内核linux2.4.20,可跟rtlinux3.2打补丁 组成实时linux系统,编译内核

# BK Id: SCCS/s.Makefile 1.36 12/01/01 20:09:06 benh

# Makefile for the linux kernel.
#
# Note! Dependencies are done automagically by 'make dep', which also
# removes any old dependencies. DON'T put your own dependencies here
# unless it's something special (ie not a .c file).
#
# Note 2! The CFLAGS definitions are now in the main makefile...
