31 * This function exists only to be pulled into libfind.a by the
32 * FINDLIB_REPLACE_FUNCS macro in configure.in. We already have
33 * AC_REPLACE_FUNCS, but that adds to LIBOBJS, and that's a gnulib thing
34 * in the case of findutils. Hence we have out own library of replacement
35 * functions which aren't in gnulib (or aren't in it any more). An example
36 * of this is waitpid(). I develop on a system that doesn't
37 * lack waitpid, for example. Therefore FINDLIB_REPLACE_FUNCS(waitpid)
38 * never puts waitpid.o into FINDLIBOBJS. Hence, to ensure that these
39 * macros are tested every time, we use FINDLIB_REPLACE_FUNCS on a function
40 * that never exists anywhere, so always needs to be pulled in. That function
46 /* does nothing, exists only to ensure that FINDLIB_REPLACE_FUNCS works. */
