* 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().
