That's an interesting approach.

Unfortunately there are a lot of other includes which still break  
things.  For example, MAC has an OSTYPE.h file which causes me  
problems all the time because it inlines actual function definitions.

What I have found in practice is that application of gcc -E | grep |  
emacs "#if 0 ... #endif" actually gets you to a workable solution  
rather quickly.  Depending on the how the file is set-up it can be  
portable.  The fftw header file I created is portable because it only  
refers to doubles and the like.

I was able to get 80+% of the sdl header done in about 1/2 hour.   
Interestigly almost all of the fallout is due to the stdio.h  
definition for FILE !

So I'm all set to experiment with it, except, of course, I can't  
successfully compile and SDL program on the MAC. :-(
