We don't need to go that far to make me happy.  I would *strongly* like 
to have a list of all targets which need fixproto.  Then I could default 
fixproto to off, and turn it on only for those specific targets (much 
more efficient).

Also, if one of these targets needed fixproto only for, say, a single 
file, that bugfix could be put into fixincludes instead (much more 
efficient).
