* configure.in: Added new MinGW-specific configure flag

	--with-win32-nlsapi.
	Added new AC_DEFINE MINGW_LIBGCJ_UNICODE.
	Add -lunicows to MinGW SYSTEMSPEC if --with-win32-nlsapi
	is set to unicows.
	* configure: Rebuilt.
	* include/config.h.in: Rebuilt.
	* win32.cc (_Jv_Win32NewString): Implemented.
	(nativeToUnicode): New helper function defined only for
	non-UNICODE builds.
	(unicodeToNative): Likewise.
	(_Jv_Win32TempString): Implemented.
	(lots): Refactored using tchar.h macros.
	(WSAEventWrapper): Use _Jv_Win32NewString.
	(_Jv_platform_initialize): Use GetModuleFileNameA instead
	of GetModuleFileName.
	(_Jv_platform_initProperties): Use _Jv_Win32NewString.
	Use temporary stack buffer instead of a heap buffer.
	* include/win32.h
	Added defines for UNICODE and _UNICODE if MINGW_LIBGCJ_UNICODE is
	defined; added tchar.h include.
	(_Jv_Win32TempString): Declared new helper class.
	(JV_TEMP_STRING_WIN32): New helper macro.
	(_Jv_Win32NewString): Declared new helper method.
	* java/io/natFileDescriptorWin32.cc (open): Use
	JV_TEMP_STRING_WIN32 instead of JV_TEMP_UTF_STRING.
	(write): Reformatted slightly.
	* java/io/natFileWin32.cc (lots): Use tchar.h macros;
	use JV_TEMP_STRING_WIN32 instead of JV_TEMP_UTF_STRING.
	(getCanonicalPath): Use _Jv_Win32NewString instead of
	JvNewStringUTF.
	(performList): Likewise.
	* java/lang/natWin32Process.cc (ChildProcessPipe):
	Use tchar.h macros.
	(startProcess): Use tchar.h macros, JV_TEMP_STRING_WIN32,
	and UNICODE environment flag for CreateProcess.
	* java/net/natNetworkInterfaceWin32.cc
	(winsock2GetRealNetworkInterfaces): Use tchar.h macros and
	_Jv_Win32NewString.
