Re: Why configure failed to search libws2_32.a in MinGW+MSYS ?

[Guo Leaveye]

As a result/summary of the original question, to make all the elsewhere code 
simple and as a replacement of AC_CHECK_LIB, I use the autoconf macro like this:

  AC_CHECK_HEADER([winsock2.h],
    [AC_DEFINE([HAVE_LIBWS2_32], [1], [Define if libws2_32 exists.])
     LIBS="-lws2_32 $LIBS"],
    [],
    [#include <windows.h>])

Which suppose that a build environment should have installed a libws2_32.a in 
case of winsock2.h can be founded in default include directories.
