I am not a proponent of third-party dependencies.

I am not a proponent of reimplementing everything but the kitchen sink
because of other people's adversity to reusing existing solutions.

I don't mind reusing existing solutions, I often do so.

But keeping dependencies on external libs to a minimum is also a concern.

Then, there is a practical issue:
I doubt libffi knows the Delphi calling conventions and the pascal
calling convention where the callee clears the stack (or was it vice
versa)? Since that is our main target group, I consider this a serious
problem.

It does support those calling conventions.

Well.
Prior to posting my statement, I checked, and it is not in the list of 
supported architectures.

But diving in the source I see it is indeed supported.
OK, that alleviates this problem.

At least I suggest that if this path is taken, then it is done using a 'manager' approach such as for the rest of functionality that introduces a dependency. This allows to re-use the work of Steve without external dependencies on common (read: x86) platforms, and maybe implement native solutions for some common platforms, for people that want it.

Michael.
