-(defmacro declare-function (fn file &optional arglist fileonly)
-  "Tell the byte-compiler that function FN is defined, in FILE.
-Optional ARGLIST is the argument list used by the function.  The
-FILE argument is not used by the byte-compiler, but by the
-`check-declare' package, which checks that FILE contains a
-definition for FN.  ARGLIST is used by both the byte-compiler and
-`check-declare' to check for consistency.
-
-FILE can be either a Lisp file (in which case the \".el\"
-extension is optional), or a C file.  C files are expanded
-relative to the Emacs \"src/\" directory.  Lisp files are
-searched for using `locate-library', and if that fails they are
-expanded relative to the location of the file containing the
-declaration.  A FILE with an \"ext:\" prefix is an external file.
-`check-declare' will check such files if they are found, and skip
-them without error if they are not.
-
-FILEONLY non-nil means that `check-declare' will only check that
-FILE exists, not that it defines FN.  This is intended for
-function-definitions that `check-declare' does not recognize, e.g.
-`defstruct'.
-
-To specify a value for FILEONLY without passing an argument list,
-set ARGLIST to `t'.  This is necessary because `nil' means an
-empty argument list, rather than an unspecified one.
-
-Note that for the purposes of `check-declare', this statement
-must be the first non-whitespace on a line, and everything up to
-the end of FILE must be all on the same line.  For example:
-
-\(declare-function c-end-of-defun \"progmodes/cc-cmds.el\"
-                  \(&optional arg))
-
-For more information, see Info node `elisp(Declaring Functions)'."
