I guess you're supposed to put "noinst_HEADERS =" at the top.

Thanks; I installed this patch in both gnulib and coreutils:

2005-07-07  Paul Eggert  <address@hidden>

        * backupfile.m4 (gl_BACKUPFILE): Use AC_CHECK_FUNCS_ONCE on pathconf.
        * same.m4 (gl_SAME): Likewise.
        Require AC_SYS_LONG_FILE_NAMES; bug reported by Gerrit P. Haase.
