/* forcefindlib
 *
 * This function exists only to be pulled into libfind.a by the 
 * FINDLIB_REPLACE_FUNCS macro in configure.in.   We already have 
 * AC_REPLACE_FUNCS, but that adds to LIBOBJS, and that's a gnulib thing
 * in the case of findutils.  Hence we have out own library of replacement 
 * functions which aren't in gnulib (or aren't in it any more).  An example
 * of this is waitpid().   I develop on a system that doesn't 
 * lack waitpid, for example.   Therefore FINDLIB_REPLACE_FUNCS(waitpid)
 * never puts waitpid.o into FINDLIBOBJS.  Hence, to ensure that these 
 * macros are tested every time, we use FINDLIB_REPLACE_FUNCS on a function 
 * that never exists anywhere, so always needs to be pulled in.  That function 
 * is forcefindlib().
