--program-suffix

[Per Starback]

In GNU Emacs 21.1:

        ./configure --help

mentions

  --program-prefix=PREFIX prepend PREFIX to installed program names
  --program-suffix=SUFFIX append SUFFIX to installed program names
  --program-transform-name=PROGRAM
                          run sed PROGRAM on installed program names

even though these actually aren't supported by the emacs installation.
It would be nice if that wasn't part of the --help output (especially
now when emacs 21 is new, so people might try --program-suffix=21
before they are ready to leave emacs 20).

Is this an autoconf issue? I have never used autoconf, so I don't
really know what I'm talking about, but the autoconf documentation
says

> In order to use these transformations, `configure.ac' must call
> the macro `AC_ARG_PROGRAM'.

and it's AC_ARG_PROGRAM that adds these lines to HELP_BEGIN which
makes it a part of the help message.  But I don't find AC_ARG_PROGRAM
used explicitly anywhere in the emacs files.  Is it not possible to
avoid calling this and getting the misleading help?
