Synopsis: gcc-3.0.4 bootstrap fails to link cpp0 together

State-Changed-From-To: open->closed

State-Changed-Why:
    This was fixed by me in a recent patch for 3.2.  3.1 and 3.0
    will have this problem because cpp0 is not integrated into
    the compiler.  This cannot easily be fixed there.
    
    The __GXX_WEAK__ stuff in cppinit.c is causing it.  If you
    can get away without that being defined correctly (it
    depends on command line options, which is the problem here) you should remove the relevant lines, or hard-code the setting, and then it should link.

>Description:
Trying to bootstrap gcc-3.0.4 on a Motorola m88k box with plain SVR4 causes the compiler to give up at building cpp0 since cppinit.o references 'target_flags' but it doesn't get linked in.

Trying to fix it myself with linking the rtlanal.o and later the $(BACKEND) stuff into it, didn't work.

It must be picking up the symbol's reference from some of the includes which doesn't make much sense to me since this is just the preprocessor!?
