cargs
A lightweight cross-platform getopt alternative that is tested on Linux, Windows, FreeBSD and macOS. Command line argument parser library for C/C++. Can be used to parse argv and argc parameters. (by likle)
optparse
Portable, reentrant, getopt-like option parser (by skeeto)

How to make programs for linux
getopt is definitely a solid option and a good choice for suggesting to beginners. I personally prefer cargs, and I never use getops anymore. You can check out cargs here: https://github.com/likle/cargs

Porting my very simple C code from Unixen/macOS to Windows
Between -std=c99 and removing these headers, you're missing time definitions (struct timeval, gettimeofday) and option parsing definitions (struct option, getopt_long). Mingw-w64 provides all this for compatibility, but MSVC has none of these, so you'll need to write replacements. I've written embeddable, public domain implementations of getopt and something like getopt_long, in case that helps. These are how I deal with option parsing portability.

getopt_long is a GNU extension, common across unix-like systems, for parsing long options. You can find libraries for functionality as well.

When I need something more sophisticated, where long options would be nice, I reach for my own Optparse.

Debian discusses vendoring again
This is bug-free and feature complete so it never needs to be updated. When I need argument parsing in a C program, I just copy-paste that into my source and massage it into place. Sometimes I cut the fprintf() stuff, or replace the isalnum, or otherwise adapt it to fit the program's needs. The point is that it becomes wholly owned by the project using it. It's a similar story for long option parsing.
What are some alternatives?
