it also  caused a bootstrap fail on powerpc-apple-darwin9.
I am bootstrapping with the following - but you might like to see if  
any other targets have a similar issue:

        inform (input_location,
                "-freorder-blocks-and-partition does not work with  
exceptions "

this is actually needed on *-*-darwin*
I've checked it on {i686,powerpc}-apple-darwin9 and x86_64-apple- 
darwin10 - although the latter does not complete bootstrap for other  
reasons, it does pass the stage that relates to this patch).

IMO, this would qualify as "obvious", may I apply it to trunk?
