> Please be more clear in your instructions, prefferably including commands that I can literally copy out of your tutorial, and paste as-is into my MSYS2 console, and run straight away without any problems, or require any changes that would make the run commands different from the ones you pasted in your tutorial.
It means you should run exactly "pacman -S --force git make diffutils texinfo mingw-w64-i686-gcc", and the next line explains why this command has a "--force" in it (if you follow the link), which generally should not be required. In fact, it's probably not required anymore already (the "--force" part), but it wouldn't hurt either. So you can still stick to these instructions.
> I'm not good with fancy C command lines, where even one tiny mistake can break the entire compilation process. I'm more used to C programs that can be compiled simply with something like "compiler.exe myprog.c" and out pops "mycode.exe". Since compiling TCC is obviously far more complex than this, please make it as easy as possible, for a noob like me to do, by writing a very clear tutorial with every step laid out, and don't assume any prior knowledge of proper use of GCC (or any other C compiler) on my part, because as I said I'm a noob..
