I received an answer from Apple. The behaviour is correct – because / 
usr/local/include is part of the built-in search directories in  
Apple's GCC 4.0.1. The cure is to add '-idirafter /usr/X11R6/include'  
– which fails in that case when this is part of a macro in a pkg- 
config file: somehow the output is sorted and -idirafter always comes  
first! So a bit of tweaking the Makefiles is needed afterwards ...
