Subject:         * archive.c (hpux_uid_gid_encode): New function.
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=ef42fa39f4dc3bf266f5578f1257200253c51dee;p=pf3gnuchains%2Fpf3gnuchains3x.git

    * archive.c (hpux_uid_gid_encode): New function.
        (bfd_ar_hdr_from_filesystem): Use it if HPUX_LARGE_AR_IDS is
        defined and the ID is greater than 99999.
        (bfd_generic_stat_arch_elt): If HPUX_LARGE_AR_IDS is defined decode
        special uid/gid fields into 32 bit values.
