#
# This GNU make makefile has been tested on:
#   Linux (x86 & Sparc)
#   OS X
#   Solaris (x86 & Sparc)
#   OpenBSD
#   NetBSD
#   FreeBSD
#   Windows (MinGW & cygwin)
#   Linux x86 targeting Android (using agcc script)
#
# Android targeted builds should invoke GNU make with GCC=agcc on
# the command line.
#
# In general, the logic below will detect and build with the available
# features which the host build environment provides.
#
# Dynamic loading of libpcap is the default behavior if pcap.h is
# available at build time.  Direct calls to libpcap can be enabled
# if GNU make is invoked with USE_NETWORK=1 on the command line.
#
# The default build will build compiler optimized binaries.
# If debugging is desired, then GNU make can be invoked with
# DEBUG=1 on the command line.
#
# For linting (or other code analyzers) make may be invoked similar to:
#
#   make GCC=cppcheck CC_OUTSPEC= LDFLAGS= CFLAGS_G="--enable=all --template=gcc" CC_STD=--std=c99
#
# CC Command (and platform available options).  (Poor man's autoconf)
