23      TARGET_EXTRA_PRE_INCLUDES, TARGET_EXTRA_INCLUDES
24 
25    As both, gcc and gfortran link in incpath.o, we cannot
26    conditionally undefine said hooks if fortran is build.
27    However, we can define do-nothing stubs of said hooks as
28    we are not interested in objc include files in Fortran.
29 
30    The hooks original purpose (see also darwin-c.c):
31     * darwin_register_objc_includes
32       Register the GNU objective-C runtime include path if STDINC.
33 
34     * darwin_register_frameworks
35       Register all the system framework paths if STDINC is true and setup
36       the missing_header callback for subframework searching if any
37       frameworks had been registered.  */
