[Bug c++/15469] Unable to compile valid code including transform() algorithm: <unknown type> is reported for the forth parameter

["relf at os2 dot ru" <gcc-bugzilla at gcc dot gnu dot org>]

Wolfgang, could you please explain the difference with the following example
from B.Stroustrup "The C++ Programming Language" 3rd edition, section 18.6.2:

template<class T> T* delete_ptr(T* p) { delete p; return 0; }
void purge(deque<Shape*>& s)
{
    transform(s.begin(),s.end(),s.begin(),delete_ptr);
    // ...
}

Note that here we pass just `delete_ptr' but not `delete_ptr<Shape>' as the
forth parameter. Why this code does not reqire explicit template class
specification while my code (that is not much different, in fact) does?
