I reviewed all of it and experimentally verified that all these
additional options indeed are supported (and have a look at the
various language annotations).

I am going to apply this patch after a round of testing over night in
my regular test cycle.

And since you seem to be attentive and interested in this level of 
detail, here is some more stuff in case you are interested. ;-)

The compiler issues the following warnings, but the respective options
are not annotated accordingly in invoke.texi:

   cc1plus: warning: command line option "-Wno-assign-intercept" is valid 
   for ObjC/ObjC++ but not for C++

   Wno-protocol, Wno-selector, Wno-strict-selector-match, 
   Wno-undeclared-selector -- ditto.

   cc1plus: warning: command line option "-Wformat-zero-length" is valid 
   for C/ObjC but not for C++

   cc1plus: warning: command line option "-Wno-nonnull" is valid for 
   C/ObjC but not for C++

   cc1plus: warning: command line option "-Wno-implicit-int" is valid for 
   C/ObjC but not for C++

   cc1plus: warning: command line option "-Wno-traditional" is valid for 
   C/ObjC but not for C++

   cc1plus: warning: command line option "-Wno-traditional-conversion" is 
   valid for C/ObjC but not for C++

    cc1plus: warning: command line option 
    "-Wno-declaration-after-statement" is valid for C/ObjC but not for C++

    cc1plus: warning: command line option "-Wno-bad-function-cast" is 
    valid for C/ObjC but not for C++

    cc1plus: warning: command line option "-Wno-strict-prototypes" is 
    valid for C/ObjC but not for C++

    cc1plus: warning: command line option "-Wno-override-init" is valid 
    for C/ObjC but not for C++

(Some of those labled C/ObjC strikingly look like ObjC only, not plain C.)
