declare strtoll in stdlib.h

[Bruno Haible]

A function returning 'long long' cannot be correctly used on 32-bit systems
without a declaration. POSIX specifies that strtoll() be declared in
<stdlib.h>. So be it. I'm applying this.


2008-10-19  Bruno Haible  <address@hidden>

        Add strtoll() declaration to <stdlib.h>.
        * lib/stdlib.in.h (strtoll): New declaration.
        * m4/strtoll.m4 (gl_FUNC_STRTOLL): Require gl_STDLIB_H_DEFAULTS.
        Set HAVE_STRTOLL.
        * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Initialize GNULIB_STRTOLL,
        HAVE_STRTOLL.
        * modules/strtoll (Depends-on): Add stdlib.
        (configure.ac): Invoke gl_STDLIB_MODULE_INDICATOR.
        * modules/stdlib (Makefile.am): Substitute GNULIB_STRTOLL, HAVE_STRTOLL.
