Are the search paths in the system access paths or the user access 
paths,  do you have always search system path for users paths selected.

You may need to make System an access path and not recursively searched.  
that is how they are found in UNIX.

The standard does not specify any behavior for releative includes or 
nested includes.  Think about it what working directory is the relative 
include start from.  the compilers?  the source code it is in,  the path 
the last header file was in?  it can be anything you want.  So relative 
positions are just that relative.
