We need to support more compilers than just GCC (e.g., MSVC on  
win32), so neither builtin_apply() nor libffi are really good options.

I believe that in conversations on this topic long ago, the gtk+  
developers considered convenience functions not worthy of the  
infrastructure treatment, because they could, indeed, be trivially  
reimplemented in bindings.  The danger there is that the code will  
become less trivial over time.

But, again, this was a long time ago, and the situation may be  
different now.
