You should be seeing this warning then:

        if (opt & (OPT_h|OPT_H)) {
                //msg added 2011-11
                bb_error_msg("option -h NAME is deprecated, use -x
hostname:NAME");
                client_config.hostname =
alloc_dhcp_option(DHCP_HOST_NAME, str_h, 0);


But it still should work, even in latest git.

Please post your exact udhcpc command line, and network capture.
