Regardless of whether or not the dynamic linkage is a violation, the header
file used has (almost) nothing to do with it.

A legal argument can be made that the relevant portions of header content
are not protectable by copyright since they are essentially a 'compilation 
of facts' and must be expressed in the way they are for compatability and 
interoperability reasons.  The only portions of header files that might
be copyrightable are complex macros or inlines, and comments. 

This argument is fairly important to us given our work on WINE. 

I'm not a lawyer, of course, but if anyone is counting on header copyright
as a mechanism for 'viral' license transmission, it would probably be a 
good idea to talk to a lawyer.
