# compile-time options
# 
# STATS allows to print out number of packets processed on CTRL-C; 
# implementation still nasty and reports per-process
# NO_DEBUG turns off some of the debug messages (DBG(...)).
# NO_LOG completely turns of all the logging (and DBG(...))
# EXTRA_DEBUG compiles in some extra debugging code
# DNS_IP_HACK faster ip address resolver for ip strings (e.g "127.0.0.1")
# SHM_MEM    compiles in shared mem. support, needed by some modules and
#            by USE_SHM_MEM
# PKG_MALLOC uses a faster malloc (exclusive w/ USE_SHM_MEM)
# USE_SHM_MEM all pkg_malloc => shm_malloc (most mallocs use a common sh. mem.
#           segment); don't define PKG_MALLOC if you want this!
# DBG_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.)
