My understanding is completely correct and the test posted in this 
thread proved it. Manually creating aa directory under /usr/include had 
aa show up in QtCreator. Manually creating a.a does not appear in QtCreator.

The directory gets walked.

This is ___NOT___ a compiler problem. I'm talking about QtCreator being 
unable to find the include files. I can compile a non-qt program from 
the command line just fine.

Please consider the previous evidence before firing off an unfounded 
response.
