If you look at their socket.h, they have a macro condition in the XPG4 compatibility
section that
renames all the socket functions to __xnet_whatever. The condition either calls
#pragma redefine extname, or #define. #define was
bad in this situation becuase PHP_FUNCTION(socket) would become
PHP_FUNCTION(__xnet_socket).
What #pragma redefine extname does, is change the name reference after compilation.
So , all references to socket,listen, bind, etc in socket.o, get renamed to the
corresponding __xnet_
xopen functions.
