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

# Always make sure 'all' is the default rule+
