I tried that, but they use two part namespaces <QuickTime/ 
QuickTime.h>.  I looked at the GCC 4.1 sources, and the framework  
includes are evaluated when the system encounters a missing header  
file.  It also mentioned looking up the header files "in context" for  
subframeworks.  In short, I don't know that framework includes can be  
spoofed with -I includes directly for everything.

The best thing I can think to do is find the 3.5 patch from Apple for  
the frameworks, and then try to backport it to 3.3.  Either that, or  
try to merge GCCXML with gcc 3.5 -- which sounds like a ton of work.

Until then, I've made this little python script to parse the makefile  
dependency list built by the system gcc and then turn that result set  
into a set of symlinks to the framework directories.  Using these  
files in my local include directory, I was able to successfully run  
gccxml and generate the xml file.  Hope this helps the next Carbon +  
GCCXML customer!  ;)

Thanks,
