#------------------------------------------------------------- -*- makefile -*-
# The following section of this makefile comes from the
# `./config/targets' file which was generated with config.status
# from `./config/targets.in'.
#------------------------------------------------------------------------------

# We keep a list of dependencies in `.depend' for each of the source
# files on which it depends.  When one of the source files is modified
# we remove its record from .depend and regenerate its dependencies,
# tacking them onto the end of .depend.  By including the .depend file
# into the makefile, we're telling make that the makefile depends on
# the dependency list in the .depend file.
#
# This is as fast as the `.d' method described in the GNU make manual
# for automatic dependencies, but has the added advantage that all
# dependencies are stored in one place.  The advantage over the
# `makedepend' program is that only those files that are out of date
# have dependency information rebuilt, and the Makefile is not
# modified.
