Maybe I misread the diff, but it says:

@emph{PDP-11 Options} (@ref{PDP-11 Options})
-@gccoptlist{-mfpu  -msoft-float  -mac0  -mno-ac0  -m40  -m45  -m10
--mint32  -mno-int16  -mint16  -mno-int32
+@gccoptlist{-mfpu  -msoft-float  -mac0  -m40  -m45  -m10
+-mint32  -mint16
-msplit  -munix-asm  -mdec-asm  -mgnu-asm  -mlra}

which looks like the last line is going away.  Or does that content appear 
through some other magic?
