Compiling this file, with mainline, gcc 4.0, or 4.1

template<typename t> void f(t a) { }
void g() { enum e { v }; f(v); }

gives this error message:

foo.cc: In function ‘void g()’:
foo.cc:2: error: no matching function for call to ‘f(g()::e)’

If the enum definition is moved out of the function, this works.  With gcc 3.2,
this works.  I didn't try 3.4.

My C++ fu is weak, and I do not know for sure that this is valid C++, although
I don't see anything wrong with it.  But either 1) it is valid and gcc should
accept it, or 2) gcc should provide a list of candidates which did not match,
since there is manifestly a function named 'f'.
