This is correct but irrelevant.

Big trouble. You used stage1 to build G++, which is a stage2 compiler.
Because stage1 is a C/Ada compiler only, *and the Java front end has C++
code*, there can be no stage2 GCJ. You want to build GCJ, so you have
to put it into stage3. This means that stage2 and stage3 are compiled
with different options, so they can't be compared. In order to do a
bootstrap comparison, you need to go to stage 4. Got it?
