  22 /* Provide stubs for the hooks defined by darwin.h
  23      TARGET_EXTRA_PRE_INCLUDES, TARGET_EXTRA_INCLUDES
  24
  25    As both, gcc and gfortran link in incpath.o, we can not
  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.  */
