Given a stage 2 build of gcc, with ./stage1/ deleted but
./stage2/ intact, is it sufficient to run 

cd ./gcc-2.5.x
patch -p < ../gcc-2.5.x-2.5.x+1.diff
make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O"
etc.
or should it be rebuilt from the start ?
Is there a good reason to start with a commercial cc 
(eg SunOS cc) ?
