Hello everyone.

I have got MSVS2008 under Windows 7. And latest "sipxtapi" sources.

When i try to compile sipXtackLib, i get some errors:

1>e:\sipxtapi\sipxtacklib\include\resparse\poll.h(45) : error C2011: 'pollfd' : 'struct' type redefinition

I opened winsock2.h and there is exists section:

#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

typedef struct pollfd {

SOCKET fd;
SHORT events;
SHORT revents;

} WSAPOLLFD, *PWSAPOLLFD, FAR *LPWSAPOLLFD;

#endif // (_WIN32_WINNT >= 0x0600)

Yes, a can to define _WIN32_WINNT as 0x0500, but i would find more best solution. Can i change poll.h, move similar definitions to 

#if(_WIN32_WINNT < 0x0600)

#endif

or i'll get other mistakes?
