No, but if you look in the C RTL Reference you will see that you need a define for either _OPEN_THREADS or _UNIX03_THREADS. > > > Another issue is that for another SSL program to compile, I had to > include the following define: > > #define _OE_SOCKETS > > Otherwise, I had en error with the AF_INET defined value.

Unfortunately, there are conflicting and sometimes slightly incompatible standards. You need to define which you want.
