# added files from freeswan-2.04-x509-1.5.3
#
# 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.
#

# pfkey_v2.c.
#
# Revision 1.37 2001/11/27 05:10:15 rgb
