main-trunck-g++: a template regression

[Max Lawson]

template<class P> struct B
{
  template<class T> void f(T& t) { t = T(); } 
};

enum ptype { t1, t2};

struct D : public B<ptype>
{
  void g(double& d) { f(d); }
};


D d;


/*
main-trunk-g++ regression:

main-trunk-g++ can't compile the above testcase, which IMHO is correct. 
It compiles compiles fine with the pre-release version.

the problem occurs because the base class B is a template: it doesn't if  
B is not a template class.

$ g++ -c  bug.cc
bug.cc: In method `void D::g(double &)':
bug.cc:10: no matching function for call to `D::f (double &)'
bug.cc:3: candidates are: B<ptype>::f<double>(T &)

Regards, Max.

P.S. with the snapshot I'm using, I can't no more take the reference of a 
temporary: is this behaviour coming from the standard ? Thanx.
