    cygwin: make <sys/socket.h> completely visible from <netinet/in.h>
    
    While POSIX mandates that certain socket types shall be defined by the
    inclusing of <netinet/in.h>, it also says that this header may also make
    visible all <sys/socket.h> symbols.  Glibc does this, and without out it,
    some packages end up requiring an additional #include <sys/socket.h>.
