Keep variable un-expanded in configure script

["Too, Justin A." <too1@xxxxxxxx>]

Hi,

I have a simple function in an m4 file that is a convenience to output information. The function takes two parameters

function foo () {
  If test $# != 2 ; then
    exit 1
  fi
}

However, Autoconf expands $#. How can I escape $#, so that it will remain as-is in the configure script? I just can't figure this one out :)

Thanks,
Justin
