# History:
# --------
#              created by andrei
#  2003-02-24  added LOCALBASE, fixed doc-dir for freebsd - patch provided
#               by Maxim Sobolev <sobomax@FreeBSD.org>
#  2003-02-25  added -DDISABLE_NAGLE (andrei)
#  2003-03-02  added -DDIGEST_DOMAIN (janakj)
#  2003-03-10  added -xcode=pic32 for module compilation w/ sun cc
#               (too many symbols for pic13)  (andrei)
#  2003-04-16  added CC_EXTRA_OPTS, s/march/mcpu, added CPU (cpu to optimize 
#               for, used only with gcc-3.x) (andrei)
#  2003-05-23  check if this makefile was already included (andrei)
#              removed -DDIGEST_DOMAIN (andrei)
#  2003-05-30  added extra_defs (andrei)
#  2003-06-06  moved compiler detection before DEFS (andrei)
#  2003-06-10  removed -m32 for gcc 3.x/sparc64  -- it will use 
#              arch. default: -m32 on solaris, -m64 on *bsd (andrei)
#  2003-09-25  added -pthread into LIBS when compiling on FreeBSD/alpha
#              and other FreeBSD arches for which no fast locking assembly
#              code exists (sobomax)
#  2003-11-08  mips1 support introduced (andrei)
#  2003-11-24  openbsd 3.4 (elf) fixes (andrei)
#  2004-07-27  darwin (mac os x) port  (andrei)

# compile-time options
#
# -DSTATS
#		allows to print out number of packets processed on CTRL-C;
# 		implementation still nasty and reports per-process
# -DNO_DEBUG
#		turns off some of the debug messages (DBG(...)).
# -DNO_LOG
#		completely turns of all the logging (and DBG(...))
# -DEXTRA_DEBUG
#		compiles in some extra debugging code
# -DDNS_IP_HACK
#		faster ip address resolver for ip strings (e.g "127.0.0.1")
# -DSHM_MEM
#		compiles in shared mem. support, needed by some modules and
#		by USE_SHM_MEM
# -DSHM_MMAP
#		use mmap instead of SYSV shared memory
# -DPKG_MALLOC
#		uses a faster malloc (exclusive w/ USE_SHM_MEM)
# -DUSE_SHM_MEM
#		all pkg_malloc => shm_malloc (most mallocs use a common sh.
#		mem. segment); don't define PKG_MALLOC if you want this!
# -DDBG_QM_MALLOC
#		qm_malloc debug code, will cause pkg_malloc and shm_malloc
#		to keep and display lot of debuging information: file name,
#		function, line number of malloc/free call for each block,
#		extra error checking (trying to free the same pointer
#		twice, trying to free a pointer alloc'ed with a different
#		malloc etc.)
# -DVQ_MALLOC
#		additional option to PKG_MALLOC which utilizes a fater then
#		qm version
#		(not true anymore, q_malloc performs approx. the same)
# -DF_MALLOC
#		an even faster malloc, not recommended for debugging
# -DDBG_MALLOC
#		issues additional debugging information if lock/unlock is called
# -DFAST_LOCK
#		uses fast arhitecture specific locking (see the arh. specific section)
# -DUSE_SYSV_SEM
#		uses sys v sems for locking (slower & limited number)
# -DUSE_PTHREAD_MUTEX
#		uses pthread mutexes, faster than sys v or posix sems, but do not 
#		work on all systems inter-processes (e.g. linux)
# -DUSE_POSIX_SEM
#		uses posix semaphores for locking (faster than sys v)
# -DBUSY_WAIT
#		uses busy waiting on the lock (FAST_LOCK)
# -DADAPTIVE_WAIT
#		try busy waiting for a while and if the lock is still held go to
#		force reschedule (FAST_LOCK)
# -DADAPTIVE_WAIT_LOOPS=number
#		number of loops we busy wait, after "number" loops have elapsed we 
#		force a reschedule (FAST_LOCK)
# -DNOSMP
#		don't use smp compliant locking (faster but won't work on SMP machines)
#		(not yet enabled) (FAST_LOCK)
# -DNO_PINGTEL_TAG_HACK
#		if enabled, To-header-field will be less liberal and will not accept
#		'tag=' (tag parameter with equal sign and without value); it is called
#		this way because such message was sighted from a Pingtel phone
# -DWITH_SNMP_MOD
#  		if enabled, allows forking of the snmp agent just before child
#  		forking (done at the top of main_loop). Needed if you want
#  		to use the snmp module.
# -DUSE_TCP
#		compiles in tcp support
# -DDISABLE_NAGLE
#		disable the tcp Nagle algorithm (lower delay)
# -DUSE_TLS
#		compiles in tls support, requires -DUSE_TCP. Please use
#		make TLS=1 instead. (tls support is highly experimental for now)
