Can´t compile with sockets

Tried to compile latest CVS (php4-200009190545) with sockets support and got the following: sockets.c: In function `php_minit_sockets': sockets.c:189: `MSG_WAITALL' undeclared (first use this function) sockets.c:189: (Each undeclared identifier is reported only once sockets.c:189: for each function it appears in.) sockets.c:201: `SO_SNDLOWAT' undeclared (first use this function) sockets.c:202: `SO_RCVLOWAT' undeclared (first use this function) sockets.c:203: `SO_SNDTIMEO' undeclared (first use this function) sockets.c:204: `SO_RCVTIMEO' undeclared (first use this function) Has anyone here used sockets? Should I submit a bug report?
