  24 # Usage: configure machine
  25 #
  26 # If configure succeeds, it leaves its status in config.status.
  27 # If configure fails after disturbing the status quo,
  28 #       config.status is removed.
  29 #
  30
  31 # Remove any leading "." elements from the path name.  When this
  32 # script is invoked from the config.status script, a new ./ gets added
  33 # to the the front of the path, resulting in a "././" prefix.  That
  34 # prefix is then recorded in the resulting config.status file, so
  35 # basically each time config.status is used, it prepends another "./"
  36 # to the filename.  This wouldn't be a problem, except that since
  37 # progname gets recorded in all the Makefiles this script produces,
  38 # move-if-changed thinks they're different when they're not.

  48 MACHINENAME is the machine to build for.  See \`etc/MACHINES'.
  49 Options are:
  50   -opsystem=SYSTEM - operating system to build for; see \`etc/MACHINES'.
  51   -prefix=DIR - where to install Emacs's library files
  52 These options have reasonable defaults (in []s), and may not be needed:
  53   -g, -O - Passed to the compiler.  If omitted, use -O only.
  54   -cc=COMPILER - Which compiler to use.  Defaults to gcc if available.
  55   -libdir=DIR - where to look for arch-dependent library files
  56   -datadir=DIR - where to look for architecture-independent library files
  57   -bindir=DIR - where to install the Emacs executable, and some friends
  58   -lisppath=PATH - colon-separated list of Elisp directories
  59   -lockdir=DIR - where Emacs should do its file-locking stuff
  60   -window_system=none or [x11, if it is installed] - what window system to use
  61   -have_x_menu=yes or [no] - include menu support under X11
  62   -gnu_malloc=[yes] or no - use the GNU memory allocator
  63   -rel_alloc=[yes] or no - use compacting allocator for buffers
  64   -highpri=N - run at N points higher-than-normal priority
  65   -lisp_float_type=[yes] or no - Support native floating point in Elisp
  66 If successful, ${progname} leaves its status in config.status.  If
  67 unsuccessful after disturbing the status quo, config.status is removed."
