#
# 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)
#
# building the pdp11, or any vax simulator could use networking support
# No Asynch I/O support for now.
