This PR adds support to the cmake build scripts so to allow building SDL with the Tiny C Compiler (tcc).
TinyCC supports the subset of C99 used by SDL and will complete the build once the --version-script linker flag is removed. The changes have been tested with various build configurations, including X11 and Wayland, and using tcc version 0.9.28rc 2025-10-27 mob@f4e01bfc on x86_64 Linux.
This allows changing out `__FILE__` in general and the file path reported in
SDL_assert specifically to not leak build machine path info, or just simply
not include the absolute path if you swap it out with `FILE_NAME` on Clang/GCC.
Fixes#14290.
Everything in SDL3 up to the ABI lock is reported as available since 3.1.3.
Everything else will be reported as since 3.2.0 (what will be the first
official release).
Also ran a Perl script over the headers to change everything to 3.1.3 that
wasn't an API function, since fnsince.pl can't manage those. If there's a
macro or datatype that has snuck in that needs to be 3.2.0 instead, we'll
have to manually fix it up, but it shouldn't be a big deal in any case.
Reference PR #11304.
We require stdbool.h in the build environment, so we might as well use the plain bool type.
If your environment doesn't have stdbool.h, this simple replacement will suffice:
typedef signed char bool;
Implemented using these sed commands on the headers:
sed -E -i'' '/SDLCALL|;/ s,([a-z])\* ,\1 *,g' *
sed -E -i'' 's,(\(.*[^\*])\* ([a-z])(.*\)),\1*\2\3,g' *
sed -E -i'' 's,\*const,* const,g' *
sed -E -i'' 's,\*SDLCALL,* SDLCALL,g' *
sed -E -i'' 's,void\(,void (,g' *
git checkout *gl*
GCC 15 development branch provides an experimental support for Windows on ARM64, which will be officially released next year, according to latest news.
I tried to compile SDL2 with this new compiler but I got a tiny problem into SDL_assert.h because it couldn't find the right platform.
However, it has been easy to fix and I included it into this PR.

(cherry picked from commit 2cb1a2d0a7)
This is just stuff I noticed while working on the wikiheaders updates. A
thorough pass over all the docs would not be terrible, and maybe a simple
script to check for consistency (does everything have a `\since` on it? etc)
might be nice, too.
