Oh, Ok. So gapi-cdecl-insert is not used for cairo in 2.12 because there are
no callback delegates there?

And how are native function calls handled in 2.12 then? I didn't see any
CallingConvention set for the native PInvoke calls. Doesn't this mean stack
memory leaks on every such call on Windows where the default is stdcall? Or
does the .NET/Mono runtime take care of this by automatically balancing the
stack if it detects a leak?

Great. I really hated this script because it magically deleted pdb files for
the libraries it was used on. 

But what will be the next gtksharp version to be released? Will it be a
bugfixing release for 2.12 or something new?
