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