warning: 'dllexport' attribute only applies to ...

[Maurizio Cimadamore]

I believe this is caused by the fact that jextract now propagates all 
diagnostics from the underlying clang parsing:

https://git.openjdk.org/jextract/pull/255

I suppose that change is what is generating the extra "noise", although 
in this case it's possible that there's indeed a real "issue" in the 
underlying header file, where __declspec is applied to some incorrect 
program element.

I guess in the future it might be possible to add a knob to select the 
level of "noise" coming from clang. In some cases it might be useful to 
see some of these messges, but I can also imagine cases where (e.g. 
during a build of something that's known to work) perhaps having too 
many messages from the underlying clang compiler might not be desirable. 
Something simple like verbose:all/info/warn/error.

Cheers
Maurizio
