duke@1: # Makefile for linking with mapfiles.

duke@1: # NOTE: Not using a mapfile will expose all your extern functions and
duke@1: #	extern data symbols as part of your interface, so unless your
duke@1: #	extern names are safe from being mistaken as names from other
duke@1: #	libraries, you better use a mapfile, or use a unique naming
duke@1: #	convention on all your extern symbols.
duke@1: #
duke@1: # The mapfile will establish versioning by defining the exported interface.
duke@1: #
duke@1: # The mapfile can also force certain .o files or elf sections into the 
duke@1: #   the different segments of the resulting library/program image.
duke@1: #
duke@1: # The macro FILES_m can contain any number of mapfiles.
