 Made following changes:

 Usage
 -----
 To add the WDMKS backend to your program which is already using 
-PortAudio, you must undefine PA_NO_WDMKS from your build file,
+PortAudio, you must define PA_USE_WDMKS=1 in your build file,
 and include the pa_win_wdmks\pa_win_wdmks.c into your build.
 The file should compile in both C and C++.
 You will need a DirectX SDK installed on your system for the
