I'm maintaining G2F an Ada binding to ImageMagick Core.
I try as well in G2F to hide the structure access by using the private 
package facility of the Ada language.
But at a low level I still need to interface the different structure 
correctly.
I would like to give the user the possibility to compile G2F with any 
version of ImageMagick supported and
otherwise generate an error at the run time if the version mismatch.
So interfacing the version 6.2 6.3...  should be  fine for any revision 
number.

Thanks, I've added the link to my bookmarks.
