The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Datatype99: C99 with Sum Types, v0.1.0
Yes, as others have already noticed, it is implemented on top of https://github.com/Hirrolot/epilepsy, a metalanguage for preprocessor metaprogramming.

Future of high-level languages
Sum types and pattern matching have already been hacked together in a preprocessor macro in C; see https://github.com/Hirrolot/datatype99.
- So far there is no evidence that Rust adds any value here. And if C is missing certain features, they can be added.

Does C have an equivalent to an algebraic data type?
It does not. There are people who have implemented such constructs in C code however, for example: https://github.com/Hirrolot/datatype99

Memory Management Reference
Nice reference but with some strange bits:
> Algebraic data types are usually represented using a heap. Because of their non-uniformity, algebraic data types are more difficult to scan.
Using a heap??? We can represent ADTs using stack as well, that's what we usually do in C and Rust.
Shameless plug: https://github.com/Hirrolot/datatype99 (a library of mine that generates type-safe ADTs for pure C99).

Pretty-Printable Enumerations in Pure C
I agree; I would especially not recommend abusing macros throughout an application codebase too much. Conceptually, Metalang99 is more of a (sub)language than a library, which also adds some entry barrier. Ideally, I see the application of Metalang99 being used "behind the scenes", e.g., encapsulated in separate code files/libraries such as Datatype99 and Interface99. This is what I (mostly) do in SmolRTSP.

lipstick: a Rust-like syntax frontend for C
I've done something similar with Datatype99 and Interface99. They are like a macro eDSL that compiles to C. The first one features algebraic data types, the second one features interfaces.

Any alternative to vala?
If you need a bit more high-level constructions, you can use the Datatype99 and Interface99 libraries. The former provides polymorphism over data, the latter -- over behaviour (I am the creator of these libraries).

Syntatic Sugar that compiles to C
OP, you might find datatype99 and its sibling projects interesting, though they mostly leverage the C preprocessor without going all the way towards defining a new language.
-
AST Implementation in C
You can use Datatype99 to represent your AST tagged union conveniently.

Rust for Linux Redux
Compared to plain C, you have ADTs which help from day to day programming. You can bring them to C (https://github.com/Hirrolot/datatype99) but I don't know if the Linux guys would allow it.
What are some alternatives?
When comparing epilepsy and datatype99 you can also consider the following projects:
