Matthew Flatt 6033237ed6 Chez Scheme: generalize __varargs to (__varargs_after <n>) 
The non-standard ARM Mac OS ABI doesn't just use a different
convention if the function has varargs: it puts each vararg in a
different place than a non-vararg argument of the same type and
position. So, `foreign-procedure` and `foreign-callable` need to know
where varargs start. A `__varargs` declaration is shorthand for
`(__varargs_after 1)`.

For PPC32 Mac OS, we retain the trick that makes varargs foreign calls
work without a `__varargs` declaration, but `(__varargs_after <n>)`
fixes up callable support --- in the extremely unlikely case that
someone needs general varargs callables on PPC32 Mac OS.

README.md

Racket is a general-purpose programming language and an ecosystem for language-oriented programming.

This repository holds the source code for the core of Racket plus some related packages. The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization.

Quick Start

Pre-built versions of Racket for a variety of operating systems and architectures, as well as convenient source distributions are available at

https://download.racket-lang.org

Racket comes with extensive documentation, including several tutorials. You can read all of this documentation, as well as documentation for third-party packages at

https://docs.racket-lang.org

Building from Source
