 @samp{restrict} to be the empty string on a pre-C99 host, or a macro
 like @samp{_FILE_OFFSET_BITS} that affects the layout of data
 structures, the definition is consistent for all include files.

 A final word of warning: Gnulib currently assumes it will be
 responsible for @emph{all} functions that end up in the Autoconf
