Like Bug #7484, when Fiddle is available, Fiddle's DL wrapper for 
DL::Function ignores :stdcall ABI. In addition, when creating callback 
closure, DL::Function wrapped by Fiddle does not set name, and 
DL::Function#name raises NoMethodError.

Hmm, when using DL::Function, the patch solves the problem.

But, when we try to shift to Fiddle from DL, since Fiddle::Function
does not still have name.
So we can not shift simply.
I think that better solution of this problem is not deceiving 
DL::Function,
but adding name to Fiddle::Function perfectly.

Goto-san, Aaron, how do you think about this?


In addition, I am actually afflicted by this shift problem now, and this
problem is serious for me.

In the commit r38243, Fiddle::Function#name is added, and 
Fiddle::Importer#import_function and bind_function set the name. The 
name attribute would be used by Fiddle version of Win32::Registry.

In r38322, Fiddle::Function#initialize can get name by using :name 
keyword argument. For example,
  Fiddle::Function.new(ptr, [], Fiddle::TYPE_VOID, name: "example")
