This isn't the right patch to apply, since Mikhail didn't fix the
strerror problem.  I have some code from Magnus Naeslund that purports
to handle the strerror issue, and will work it up into a patch real soon
now.

FWIW, Magnus says this works:

#define SOCK_STRERROR my_sock_strerror

const char* my_sock_strerror(unsigned long eno){
    static char buf[512]; // i know, not threadsafe
    if (!FormatMessage( 
            FORMAT_MESSAGE_FROM_SYSTEM | 
            FORMAT_MESSAGE_IGNORE_INSERTS,
            0,eno,
            MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
            buf,sizeof(buf)-1,
            0
           )){
      sprintf(buf,"Unknown socket error(%u)",eno);
    }
    buf[sizeof(buf)-1]='\0';
    return buf;
}


Anyone have any objections to it?
