Sorry if that sounded like whining. It's just the way it is. (Compilation 
regressions are for package regression testers like me, what bootstrap 
failures are for gcc developers.)

Right.

If anyone really feels compelled to do something about it, below is info 
about the two PRs that broke compiling the lib. I don't know what more is 
broken behind them.

PR 9457: introduced between 2003-1-12 and 2003-1-30. Testcase:

PR 9453: ICE introduced between 2003-01-05 and 2003-01-12 (was an error on
01-05, which also was wrong, but I think Kriang fixed that; it's the ICE
that's bothering me in the first place). Testcase:
------------------------
template <typename> class X {
  private:
    struct Inner;

    template <typename R>
    friend typename X<R>::Inner * foo () { return 0; };
};
template class X<void>;

struct U {
    void bar () { foo<void> (); };
};
