Here's what's defined in the winsock2.h file:
---- snip
#if(_WIN32_WINNT >= 0x0600)
/* Event flag definitions for WSAPoll(). */
#define POLLRDNORM 0x0100
#define POLLRDBAND 0x0200
#define POLLIN (POLLRDNORM | POLLRDBAND)
#define POLLPRI 0x0400
#define POLLWRNORM 0x0010
#define POLLOUT (POLLWRNORM)
#define POLLWRBAND 0x0020
#define POLLERR 0x0001
#define POLLHUP 0x0002
#define POLLNVAL 0x0004
---- snip
So if I read that right, the net effect is:
#define POLLIN 0x0300
#define POLLOUT 0x0010
#define POLLERR 0x0001
..and what we have in FLTK is:
# define POLLIN 1
# define POLLOUT 4
# define POLLERR 8
..which is quite different.
I guess that's why they call it winsock "2" ?

I think that error line in Fl_win32.cxx is part of Fl_X::make()'s
definition,
so not sure how the "friend class Fl_Group" would help..?
