This would have to be done in winegcc, with appropriate configure
checks. It's probably easier to change the address to leave more room.

Alexandre, this is very far out of my area of expertise.  The suggestion of 
max-page-size came from Tijl (CCed).  If I understand what you are suggesting 
is:
 1) Change winegcc to include the max-page-size fix for all dlls on amd64?, or
 2) Change the image base so that it works on both i386 and amd64 (with super 
pages)?

If (1) then could you please point me in the right direction.  I have no idea 
where to start.  If (2), I though the image base was prescribed by Microsoft 
and couldn't be changed (and if it could then the other layouts also need to 
be taken into account).  Either way I also have no idea where to start.  I 
know enough to know I know very little.

Regards

The base address can be changed, it only needs to be in the same general
area, without overlapping with other builtin dlls.
