Can you give me any references?  I googled it, and couldn't find any  
recommendations one way or another.  But to me, the word "fast" is a  
recommendation.

It probably is a relic of QD3D.  I expect that as long as the  
alignment of the header agrees with the alignment used to build Quesa,  
then it shouldn't matter.  So I think we can wrap it as you suggest.

I don't know why, and wouldn't object to changing it.  (I always use  
Quesa as a framework.)  However, I don't think it's exactly true that  
Xcode doesn't allow different libraries to be used in different  
configurations.  You can use a trick of putting symbolic links in the  
build product Release and Debug folders, and then putting one of those  
links in the project with a Build Product-relative path.
