The AC_LIBTOOL_WIN32_DLL macro has been deprecated for a while and code should call LT_INIT with win32-dll instead. Update the calls to match. The generated code is noisy not because of substantial differences, but because the order of some macros change (i.e. instead of calling AS and then CC, CC is called first and then AS).
