# $Log: Makefile.fs2_4,v $
# Revision 1.9  2005/05/20 16:47:26  mcr
# 	added missing routines for 2.4 compilation.
#
# Revision 1.8  2005/05/20 03:19:18  mcr
# 	modifications for use on 2.4.30 kernel, with backported
# 	printk_ratelimit(). all warnings removed.
#
# Revision 1.7  2005/05/20 02:46:30  mcr
# 	compatibility for 2.4 kernel.
#
# Revision 1.6  2005/04/14 20:48:30  mcr
# 	added snprintf to build list for 2.4.
#
# Revision 1.5  2004/09/14 00:03:47  mcr
# 	use assembly code on i586/i686 for zlib.
#
# Revision 1.4  2004/07/22 02:09:12  mcr
# 	do not use export-objs on ipsec_alg.c, as the rule does not
# 	work with VPATH for silly reasons.
# 	Instead, define -DEXPORT_SYMTAB directly.
#
# Revision 1.3  2004/07/19 01:48:54  mcr
# 	adjustment of Makefile to use split OX/O_OBJS.
#
# Revision 1.2  2004/07/18 16:17:10  mcr
# 	list ipsec_alg.o as both an export object and an object
# 	that has to be compiled.
#
# Revision 1.1  2004/07/10 19:11:18  mcr
# 	CONFIG_IPSEC -> CONFIG_KLIPS.
#
# Revision 1.3  2004/02/24 17:17:04  mcr
# 	s/CONFIG_IPSEC/CONFIG_KLIPS/ as 26sec uses "CONFIG_IPSEC" to
# 	turn it on/off as well.
#
# Revision 1.2  2004/02/22 06:50:42  mcr
# 	kernel 2.6 port - merged with 2.4 code.
#
# Revision 1.1  2004/02/14 21:59:19  mcr
# 	split up Makefile into kernel specific versions.
#
# Revision 1.68  2003/12/15 20:38:11  mcr
# 	make sure that IPIP is always on.
#
# Revision 1.67  2003/12/15 15:42:27  mcr
# 	make sure that ESP is always on, and AH is no more.
#
# Revision 1.66  2003/12/13 04:09:21  mcr
# 	AH transform removed.
#
# Revision 1.65  2003/12/11 20:15:04  mcr
# 	refactored the xmit code, to move all encapsulation
# 	code into protocol functions. Note that all functions
# 	are essentially done by a single function, which is probably
# 	wrong.
# 	the rcv_functions structures are renamed xform_functions.
#
# Revision 1.64  2003/12/06 21:21:38  mcr
# 	split up receive path into per-transform files, for
# 	easier later removal.
#
# Revision 1.63  2003/11/07 02:58:06  mcr
# 	backout of port-selector and X.509 patches
#
# Revision 1.61  2003/06/22 21:07:46  mcr
# 	adjusted TAGS target in makefile to be useful in 2.00 source layout.
#
# Revision 1.60  2003/05/03 23:45:23  mcr
# 	rm .o.flags and generated version.c file.
#
# Revision 1.59  2003/02/12 19:32:47  rgb
# Added ipsec_xmit to the list of object files.
#
# Revision 1.58  2003/01/03 00:36:44  rgb
#
# Added emacs compile-command.
#
# Revision 1.57  2002/11/08 23:49:53  mcr
# 	use KERNEL_CFLAGS and MODULE_CFLAGS to get proper list
# 	of include directories.
# 	This also eliminates some of the guesswork in the kernel
# 	configuration file.
#
# Revision 1.56  2002/11/08 23:23:18  mcr
# 	attempt to guess kernel compilation flags (i.e. list of -I)
# 	by using some magic targets in the kernel makefile.
#
# Revision 1.55  2002/11/08 10:13:33  mcr
# 	added additional include directories for module builds for 2.4.19.
#
# Revision 1.54  2002/10/20 06:10:30  build
# CONFIG_NOHIGHMEM for -Wpointer-arith RPM building issues.
#
# Revision 1.53  2002/10/17 16:32:01  mcr
# 	enable standard AS rules.
#
# Revision 1.52  2002/10/06 06:13:44  sam
# Altering order of includes, so that architecture-specific header files,
# used for building RPM modules specifically, are processed first.
#
# Revision 1.51  2002/10/05 15:06:38  dhr
#
# - To allow for gcc3.2 (used in Red Hat Linux 8.0):  adjust CFLAGS (set
#   by kernel machinery) to use -falign-functions= in place of
#   -malign-functions=.  Eliminates a warning (fatal with -Werror).
#
# - When CONFIG_HIGHMEM is on, -Wpointer-arith will warn about
#   include/linux/highmem.h.  Since this is fatal with -Werror, we
#   suppress -Wpointer-arith if CONFIG_HIGHMEM is set.
#
# Revision 1.50  2002/09/16 21:19:45  mcr
# 	enable -Werror for production - this helps a lot (found a bug in ipsec_rcv.c)
#
# Revision 1.49  2002/07/29 05:12:39  mcr
# 	get rid of some extraneous stuff, now handled by a prefix
# 	Makefile when building as a module.
#
# Revision 1.48  2002/07/28 23:13:49  mcr
# 	set KLIPS_TOP and use it instead of ../..
# 	if KLIPSMODULE, then include a bunch of stuff defined in Makefile.inc
# 	that gets us the "typical" configuration that we want.
#
# Revision 1.47  2002/06/02 21:51:41  mcr
# 	changed TOPDIR->FREESWANSRCDIR in all Makefiles.
# 	(note that linux/net/ipsec/Makefile uses TOPDIR because this is the
# 	kernel sense.)
#
# Revision 1.46  2002/05/14 02:35:51  rgb
# Added file pfkey_v2_ext_process.c.
#
# Revision 1.45  2002/05/13 17:21:40  mcr
# 	mkdep dies when given a -I to a directory that does not exist.
# 	arch/${ARCH}/include is for UM arch only, so include it for that
# 	ARCH only.
#
# Revision 1.44  2002/04/24 20:38:12  mcr
# 	moved more stuff behind $KLIPSMODULE=y to get static linking to work.
#
# Revision 1.43  2002/04/24 09:16:18  mcr
# 	include local Makefile.ver as well as FS_rootdir version.
#
# Revision 1.42  2002/04/24 08:50:08  mcr
# 	critical patch is to set TOPDIR with :=.
#
# Revision 1.40  2002/04/24 00:41:07  mcr
# Moved from ./klips/net/ipsec/Makefile,v
#
# Revision 1.39  2002/01/17 04:39:40  rgb
