makefile

Linux 1.0 内核C源代码 Linux最早版本代码 由Linus Torvalds亲自书写的

# Makefile for the linux networking.
#
# 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 definition is now in the main makefile...

# only these two lines should need to be changed to remove inet sockets.
# (and the inet/tcpip.o in net.o)
