Though I never really thought about it, I always suspected that include
files didn't follow a path like libraries. So I never  worried to much
about about possible left-overs in include directories... Well - I was
wrong!

That was the cause of all trouble! Found an old pmt/pmt/h, removed it,
recompiled osmosdr. All is well now. 

Thanks! Not only does everything work now, I learned something new
about compiling and debugging.

Cheers, Vasil!
