 At header-file <boost/asio.hpp> usage there is a compilation error:

 SOCKET type equal INT_PTR (/usr/i686-pc-mingw32/sys-
 root/mingw/include/mingw_inc/_socket_types.h)
 On win32 INT_PTR equal int (/usr/i686-pc-mingw32/sys-
 root/mingw/include/basetds.h)

 It possible usage boost::enable_if for detect this collision.
