As Paavo Helde notes in his reply it's called a trampoline.
Trampolines were used in Borland Pascal's windowing library, and I guess
they did the same in Borland C++.
One C++ expert that's done some work on trampolines: Andrei
Alexandrescu. Andrei is or was much like Bjarne. One could e-mail him
and he'd answer to the best of his ability. As I recall I've only
¹intersected his path five times, but I think it's enough to say that
the opinion that you can mail him and will probably get help with this
is an informed one.
One C++ programmer who's submitted or at least started on a proposal for
standardization of C++ trampoline generation: the good Puppy (I don't
recall his real name) in the C++ Lounge at Stack Overflow.
You could visit the Lounge and air the question. Chances are that the
puppy wrote some implementation for his proposal. As I recall he
attended one committee meeting for this.
¹ I provided some feedback on the first ScopeGuard implementation
(Andrei helped the original inventor Petru Marginean publish a DDJ
article about it and provided some helper functionality), namely that
their use of `__LINE__` at that time didn't work with a special option
in Visual C++, and that they swallowed exceptions; I was one of the
reviewers of his "Mojo" framework for C++03 move semantics, where I
failed to see the big problem that someone else noticed, and Andrei then
corrected, and I even at first failed to compile it, but Andrei helped
me out; I fixed the failure/succeess return code of `WinMain` for the D
language, where Andrei and Walter Bright somehow, very perplexingly, got
that wrong; as a clc++m contributor I engaged in an escalating debate
with Andrei about SESE versus SEME, where I used so strong words that a
posting was rejected and I had to apologize, and the moderators
explained that they had accepted the posting without looking because it
was two experts debating (that was the first time I was ever called a
C++ expert); and, but I'm not sure I remember this correctly, but
something like this, later as clc++m moderator I accepted a posting that
included a link to an illegal PDF of Andrei's "Modern C++ Design" book,
and he was absolutely not pleased about that.
