   5 # There's not a lot we can do to build reliably in the face of many
   6 # available configuration options.  To be as low-overhead as possible,
   7 # we follow the following scheme:
   8 #
   9 # * Configuration is only re-run when an autoconf source file (such as
  10 #   "configure" or "config.sub") is changed.
  11 #
  12 # * "config.status" is run to rebuild Makefiles and .h files if an
  13 #   autoconf-parsed file (such as Makefile.in) is changed.
  14 #
  15 # * If MKUPDATE != "no", "make install" is only run if a build has happened
  16 #   since the last install in the current directory.
