Re: [RFA] new tcp_open


Those warnings were always there.  My patch reverted those lines back
to what was there before.  However, it does appear that changing the char * 
cast to a void * would eliminate the warning and should probably work 
everywhere.  Systems that based their sockets on very old BSD have char * 
instead of void * in their setsockopt prototypes.

I tested void * on Linux and Windows and neither complain.  I have been
trying all day on a Solaris box, but it just can't seem to compile
GDB in less than a couple of days.  How can a big Ultrasparc with
a load average of 0.08 take > 12 hours to build GDB???
