        * modules/atoll: New file.
        * lib/stdlib.in.h (atoll): New declaration.
        * lib/atoll.c: New file, from glibc with modifications.
        * m4/atoll.m4: New file.
        * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Initialize GNULIB_ATOLL,
        HAVE_ATOLL.
        * modules/stdlib (Makefile.am): Substitute GNULIB_ATOLL, HAVE_ATOLL.
