e_pluschauskas I noticed that after updating SDL to 2.0.6 my application now exports SDL_main. At GitHub SDL mirror (branch 2.0.5) SDL_main prototyped as extern C_LINKAGE int SDL_main(int argc, char *argv[]); but at branch 2.0.6 prototype is extern C_LINKAGE DECLSPEC int SDL_main(int argc, char *argv[]);
