Is this the same compiler that famously spurred Richard Stallman to create GCC [1] when its author "responded derisively, stating that the university was free but the compiler was not"?
It seems to be free now anyway, since 2005 according to the git history, under a 3-clause BSD license.
It's interesting that they have a Raspberry Pi GPU backend, but neither an ARM backend nor any modern ISA. (such as x86-64, Aarch64, etc.) Is there any example program that actually runs on the rpi gpu? I skimped the website, but it is only mentioned in the release notes.
tl;dr: A kit for targeting several old or old-ish platforms, with code in some languages popular in the 1980s: C89 (ANSI C), Pascal, Modula 2, Basic. A 'kit' here means: frontend, codegen, support libraries and some tools. This is apparently known as being the default toolchain for Minix 1 and 2.
But - the repository is not "everything you need"; it actually relies on a lot from an existing platform - GCC, Lua, Make, Python etc. So, you would typically use this to cross-compile it seems.
It doesn't rely on gcc. Any C compiler will do. The rest is there to build it on " Linux, OSX, and Windows using MSYS2 and mingw32". Indeed for cross-compilation, as it won't run on CP/M.

Contrary to common understanding LLVM wasn't the very first one, ACK also not, there are others predating it when diving into compiler literature.

That is not very surprising since Tannenbaum is a professor there and cowrote wrote the ACK and wrote Minix.
