There more. If for example /usr/X11R6/include is specified in C_INCLUDE_PATH
(or accordingly CPLUS_INCLUDE_PATH for C++) it is also treated as system 
header directory. So I'm getting warning when -I/usr/X11R6/include is 
specified in command line. Perhaps it would be better to  limit this warning 
to list of system include directories before adding ones from C_INCLUDE_PATH 
or CPLUS_INCLUDE_PATH (or even to ones which are processed by fixincludes)
