But if the C++ front-end requires ISO C90, then you'll need the 4 (or
3, depending on how you count) passes bootstrap for java anyway.
Either you downgrade the C++ front-end all the way back to K&R or
there is no need to bother since you'll have to do the first compile
with the pass1 xgcc anyway.
You have a limited number of possibilities here:
- go 4-pass for java
- downgrade the c++ frontend all the way to the C front-end required
level, ie K&R
- change the c++ frontend back to ISO C _and_ upgrade the requirements
to ISO C
Moving the C++ frontend to iso C without upgrading the requirements
won't do.
