Ok. I will update the project accordingly.
I do not have problems in compiling.

Which version of Xcode do you have?

As an aside I would prefer the choice of the
graphical backend (QTTEXMACS, X11TEXMACS, AQUATEXMACS) not to be  
performed at the level of config.h but with a -D directive to the  
compiler.
Can I commit a change at this effect?  This would allow to have  
multiple targets (Qt,X11,Cocoa) in Xcode without the need to  
reconfigure.

Qt has already a buffer to handle graphics, so we are duplicating the  
buffering which give a small penaly. I will wait the reimplementation  
to be finished before trying to measure its performance.
Under X11 we can disable double-buffering so there will be no overall  
penalty. Under Mac and Windows this does not seems allowed nor I can  
peek in the buffer to have some custom handling of its pixels so we do  
not have really choice (unless we redesign the shadowing mechanism in  
TeXmacs). Cocoa allow to peek in the double-buffer so there is the  
possibility to write specific code to optimize the rendering under Mac  
if we feel the need.

I prefer to wait until I finish all the changes.  When I'm ready I  
will post a patch with the redesigned graphical handling. For the  
moment it draws just garbage on screen....
