Hello:


----------------------------------------------------
template <class A>
void foo(const A& a);

template <class RET, class ARG1>
void foo(RET (&)(ARG1));


float decl(int);

void bar(void)
{
  foo(decl);
}
----------------------------------------------------
lambda.cc:12: error: call of overloaded 'foo(float (&)(int))' is ambiguous
lambda.cc:2: note: candidates are: void foo(const A&) [with A = float ()(int)]
lambda.cc:5: note:                 void foo(RET (&)(ARG1)) [with RET = float, 
ARG1 = int]


I'm pretty sure that the latter overload is more specialized than the former, 
and EDG agress with me. Not sure if it is a regression.
