# 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

mapfile_default_rule: all
