That might be true (depending on what version of GCC do you use), but           
even if it is so, the necessary header is included by the preprocessor          
before anything else, because the specs file tells it to do so with the         
-isystem switch.                                                                

I'm using gcc 2.7.2.1 with (recently installed) binutils 2.10; could
this combination have introduced a subtle misfeature with respect to
the specs file?  (I plan to upgrade to 2.95.3 tonight, to see if that
makes any difference).
