Jan, can you resend the your patch set, I think you forgot a commit.
The first patch does not apply, in particular this hunk:

--8<---------------cut here---------------start------------->8---
 		  ;; Things we don't need:
 		  ;; BaseClasses - contains libraries from Windows SDK
 		  ;; we don't need it, at least not now.
-                  (list "BaseClasses" "bin" "g7221" "ilbc" "milenage"
+                  (list "BaseClasses" "g7221" "ilbc" "milenage"
 			"speex" "threademulation" "yuv" "bdsound"
-			"gsm" "lib" "mp3" "resample" "srtp" "webrtc"
+			"gsm" "mp3" "resample" "srtp" "webrtc"
                         ;; Keep only resample, build and README.txt.
                         "build/baseclasses" "build/g7221" "build/gsm"
 			"build/ilbc" "build/milenage" "build/resample"
--8<---------------cut here---------------end--------------->8---

Cheers!
