Turns out that the latest version of SDL 1.2 is version 1.2.15, released 
in 2012 (!), and that what I’m actually using is 
https://github.com/libsdl-org/sdl12-compat. This is a compatibility 
layer, which *pretends* to be SDL 1.2.x (in this case 1.2.50), but which 
uses SDL 2.0 under the hood.

The original SDL 1.2 is not packaged in my distro (openSUSE Tumbleweed).
