Hello!

I'm trying to build an application with statically linked libcurl in Visual
Studio 2010 on Windows XP. The project builds successfully, but when i run
the application, i get this message:

"The procedure entry point WSAPoll could not be located in the dynamic link
library WS2_32.dll"

Some googling tells me that this is a known problem in libcurl on XP, and
could be solved by defining:

_WIN32_WINNT 0x0500

However, this results in a wall of errors:

I also tried this (based on some other mailinglist post), but with the same
problem:

#define WINVER 0x0502
#define _WIN32_WINNT 0x0502
#define _WIN32_WINDOWS 0x0502

I tried both to add the different preprocessor definitions to config-win32.h
and to set them directly in the Visual Studio project properties, but
nothing works.

What is going on here?

Thanks in advance!
