PATCH: dlls/winsock/socket.h portability fix

[Gerald Pfeifer]

After the recent changes to dlls/winsock/socket.h, I'm getting the
following build failure on FreeBSD 5.3:

  /usr/bin/gcc -c -I. -I. -I../../include -I../../include  -D__WINESRC__  
  -DUSE_WS_PREFIX -D_REENTRANT -fPIC -Wall -pipe 
  -mpreferred-stack-boundary=2 -fno-strict- aliasing -gstabs+ 
  -Wdeclaration-after-statement -Wpointer-arith -g -O2 -o socket.o socket.c 
  socket.c:335: error: `EAI_NODATA' undeclared here (not in a function) 
  socket.c:335: error: initializer element is not constant socket.c:335: 
  error: (near initialization for `ws_eai_map[5][1]')

The following patch fixes this.

Gerald

ChangeLog:
On some systems like FreeBSD, EAI_NODATA is defined in <lwres/netdb.h>,
so include this if present.
