# -DKLIPS enables interface to Kernel LINUX IPsec code
# -DDEBUG enables debugging code, allowing for debugging output
#    (note that output must also be selected at runtime, so it is
#    reasonable to always define this)
# -DGCC_LINT uses gcc-specific declarations to improve compile-time
#    diagnostics.
# -DLEAK_DETECTIVE enables crude code to find memory allocation leaks.
# -DDODGE_DH_MISSING_ZERO_BUG enables kludge to remain interoperable
#    with Pluto from FreeS/WAN 1.00 and before.
# -DNO_RSA, we're American.  Eliminates use of RSA.
# -DOLD_RESOLVER needs to be set unless resolver is new enough to have
#    the new res_ninit etc. interface with statp arguments.  RH6.2
#    seems to be "old".

# The following are best left undefined -- each can be overridden at runtime
# if need be.
# -DPORT=n sets the default UDP port for IKE messages (otherwise 500)
# -DSHARED_SECRETS_FILE=string overrides /etc/ipsec.secrets as the
#    default name of the file containing secrets used to authenticate other
#    IKE daemons.  In the Makefile, two levels of quoting are needed:
#    -DSHARED_SECRETS_FILE='"/etc/ipsec.secrets"'
# -DDEFAULT_CTLBASE=string overrides /var/run/pluto as default directory
#    and basename for pluto's lockfile (.pid) and control socket (.ctl).
#    Double quoting may be needed.
