Great, but if binary are excluded from the libcurl license, then binaries  
don't have any license and are unusable. Besides, legally I don't think he  
can change the interpretation of his license without changing its text.  
I'd recommend kindly asking him to grant you/D the right to use libcurl  
under the BOOST license, for legal reasons.
