Subject: [PATCH 1/2] Tell cmake to use c99 to fix build with GCC 15

GCC 15 uses c23 instead of c17 by default. Apparently c23 is not backwards compatible to older C standards... This prevented me from easily compuling simh so I added a setting to tell cmake to use c99 fixing the compiling errors.

Fixes #490

Subject: [PATCH 2/2] Add missing package to dependency checker for arch linux

I added the missing dependency sdl2_ttf for arch linux in the dependency checker as after using the checker I still needed to manually install that to compile.
