[Bug 41705] build fails in dpnet

https://bugs.winehq.org/show_bug.cgi?id=41705

--- Comment #2 from Bruno Jesus  ---
> From winsock.h (WS prefix removed):

404 typedef struct sockaddr
 405 {
 406         u_short sa_family;
 407         char        sa_data[14];
 408 } SOCKADDR, *PSOCKADDR, *LPSOCKADDR;
> From dpaddr.h:

30 typedef struct sockaddr SOCKADDR;

The definitions should be compatible. Could this be related to older compilers
or a missing compiler option?
