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.

In terms of ISO-complianceness, perhaps don't expect much. It basically C89 (the C99 support is still incomplete), and for C++... most likely not even C++98 - compliant.

Popularity of DOS/4GW made Win95 game compat easier, but with higher stakes
> You will also want to start with a 16-bit C compiler like Borland Turbo C or Microsoft C
The parent post mentioned they're going to use OpenWatcom which is an actively developed[0] C and C++ compiler that targets 16bit DOS (among others).

#pragma once / header guards / C++ committee.
Despite the lack of feature support, the compiler is still updated to this day, and still does support DOS, Windows, Linux, and OS/2, so it's modern in the sense of maintenance, just not really standards support. If you got further questions, I can send you the Discord link. They are pretty friendly.

Rust is Boring
My advice is, when you feel you need that challenge, install DOSBox or DOSBox-X and Open Watcom C/C++, DJGPP, or gcc-ia16 and do some retro-programming. You'll also get the fun of being able to do low-level hardware twiddling and rely on DOS being so simple that it's effectively an RTOS.

Build C/C++ programs to run on homebrew 286?
If you want to build under Linux, I would recommend you look at Open Watcom. It's the best open source 16-bit x86 C compiler, IMHO.

"My Reaction to Dr. Stroustrup’s Recent Memory Safety Comments"
I have recently found out that Watcom C still exists. And not just exists, but there are plenty of commits.

Win16 Retro Development
I should note, that OpenWatcom 2.0[1] is far better for supporting more recent C and C++ code, modern hosts and tooling, but still able to compile into 16 bit code. It is also actively maintained. Instead of MASM I recommend JWasm[2] + Jwlink[3]. Back in time I did a fork[4] of JWasm that has cleaner build system (CMake).

Rendering like it's 1996 - Baby's first pixel
If you want to run this in DOS: the code under src/should actually compile with this OpenWatcom fork via the -za99 flag. MiniFB however will not compile. You'd have to palettize the output pixel buffer to 256 colors and then blit it to 0xa000if you fancy that.

Falsehoods programmers believe about undefined behavior
GCC, clang or maybe watcom? You wouldn't find it there (before invention of AGI, but that would be entirely different can of worms).

VisiCalc
Emu2 allows to run 8086 software in text mode too, such as Turbo Pascal: https://github.com/dmsc/emu2 But what I'd like would be to have a Sixel backend for the EGA/VGA modes. Then by just using an xterm, ever over OpenSSH, I could run old retro DOS games under that.
