It would be much easier if setup.py could link against the import-lib
of libcurl. As it is written now (static libcurl.lib), it must link with all
the external libs libcurl depends on. E.g. gdi32.lib, wldap32.lib, winmm.lib
etc. So why isn't 'CURL_STATICLIB' removed by default?

For my own, I've patched setup.py like this:

---------------

The "-D_WIN32_WINNT=0x0501" should IMHO be default since inet_ntop()
is not present in ws2_32.dll on Win-XP. Only Vista+. Running any python
script using pycurl now gives this cryptic message:

    import sys, socket, pycurl
ImportError: DLL load failed: The given function was not found.

I.e. a missing "inet_ntop" in ws2_32.dll.
