 Clib2 now contain also libauto with almost all OS4 components. We'll try to keep them updated.
 
+### libpthread

+Clib2 now contain a native pthread implementation. However pthread functions are in libc and libpthread is just a stub.
+That's because pthread functions are used (and will be used more in the future) internally and they are needed by libc.  
+libpthread.a is however present as stub to avoid old program stop compiling claiming this library
