[objc-improvements] Initial Check-In

This is the first check-in to the objc-improvements-branch (after its 
creation).
It is quite messy because it consists of two things:
  (1) Apple's extensive ObjC changes being merged back
  (2) A merge from TOT (objc-improvements-merge-20030722 tag).  This 
was done to
      verify that there are no regressions between 
objc-improvements-merge-20030722
      and objc-improvements-branch

Obviously, much more detailed ChangeLog entries (and diffs!) will need 
to be prepared when we merge
objc-improvements-branch into the mainline.  :-)  Also, most of this 
work will still have to be ANSI-fied
(now that the fatwah on ANSI syntax has been lifted.)

Many new test cases have been added into gcc/testsuite/objc.dg.  They 
all fall into one of
3 categories:
  (1) Test cases that succeed with the GNU as well as the NeXT runtime.
  (2) Test cases marked with 'target *-*-darwin*', since they rely on 
NeXT runtime features
  (3) Test cases which _should_ work on GNU, but for some reason do 
not.  (NB: They do work on Darwin.)
      This must be investigated further.

At this point, it would be very helpful if GNUStep developers could 
check out the objc-improvements-branch,
build the compiler, and identify any problems that arise.  If you come 
up with any fixes that affect only the GNU
mode (and leave the NeXT mode alone), please go ahead and check those 
in; I trust you. :-)  If a proposed fix
affects the NeXT mode in any way, I kindly ask that you post a diff to 
gcc-patches so that I may have a quick
look-see.

Thank you,
