# Notes:
#
# This makefile provides automatic handling of different system
# platforms. Therefore it is required to set the environment
# variable SYSTEM_NAME according to the actual platform.
# Currently, these platforms are supported:
#   IRIX
#   Linux
#   Solaris
#   ... and most other UNIX platforms ...
#
# If CFLAGS or LDFLAGS are changed for a subsequent invocation of make,
# object files and binaries are NOT remade automatically with the new
# options! Use "make clean" first ...
#
# To make mp4auenc and mp4audec, type:
#   make all
#
# To allow make running e.g. 4 jobs at once, type:
#   make MFLAGS=-j4
#
# On most platforms, the default compiler is g++. To use the platform's
# native compiler (e.g. cc) instead, type:
#   make MAKE_CC=native
# and to use gcc, type:
#   make MAKE_CC=gnu
#
