Here's what I came up with.  Note that these notes reference (as of yet)
nonexistent (online) 3.4 docs.  Is this acceptable?  I'm trying to avoid
repeating stuff that's already in gcc/doc/invoke.texi.  Please let me  
know
if I should revise this or other aspects; I'll hold off on committing  
for
now.

Thanks,

numerous
!         bug fixes and enhancements previously available only in  
Apple's
!         version of GCC.  These include:
!         <ul>
!           <li>Structured exception  
(<code>@try..@catch..@finally</code>,
!               <code>@throw</code>) and synchronization  
(<code<@synchronized</code>)
!               support.  These are accessible via the  
<code>-fobjc-exceptions</code>
!               switch; as of this writing, they may only be used in  
conjunction with
!               <code>-fnext-runtime</code> on Mac OS X 10.3 and later.

!           <li>An overhaul of <code>@encode</code> logic.  The C99  
<code>_Bool</code>
!               and C++ <code>bool</code> type may now be encoded as  
<code>'B'</code>.
!               In addition, the back-end/codegen dependencies have  
been removed.</li>
!           <li>An overhaul of message dispatch construction, ensuring  
that the
!               various receiver types (and casts thereof) are handled  
properly,
!               and that correct diagnostics are issued.</li>
!           <li>Support for "Zero-Link" (<code>-fzero-link</code>) and  
"Fix-and-Continue"
!               (<code>-freplace-objc-classes</code>) debugging modes,  
currently available

<code>nil</code>.  This is
