Fix asctime_r warning with MS-Windows
    
    Problem reported by Ian Abbott in:
    http://mm.icann.org/pipermail/tz/2016-February/023291.html
    * Makefile (CFLAGS): Add comment about new -D option.
    * private.h (HAVE_DECL_ASCTIME_R): New macro.
    (asctime_r): Depend on this, not on HAVE_POSIX_DECLS.
