dnl These are alternate definitions of some macros, which produce

dnl strings in the output marked with "@@@" so we can easily extract

dnl the information we want.  The `#' at the end of the first line of

dnl each definition seems to be necessary to prevent m4 from eating

dnl the newline, which makes the @@@ not always be at the beginning of

dnl a line.
