/* to avoid warnings/errors, you will have to fix the TCP/IP headers :
 *
 * in case of TCP/IP 1.2.1:
 * - in netlib.h, remove the useless SIGALRM definition
 * - in utils.h, replace // comments by regular ones
 * (both headers are not included directly but via types.h) *
 *
 * in case of TCP/IP 2.0:
 * - in types.h, remove the useless SIGALRM definition
