OK, I've changed the code in SDL_Version.e following Greg's advice. It works for me. I've changed from C_UINT to C_UINT8, and rewrote the SDL_GetVersion() function as Greg has shown. I tested it and it works for me. I've also pushed these changes on github. I had forgotten to update the values for the current SDL version in the SDL_Version.e code, but that has been fixed too.

include std/ffi.e 
include std/machine.e --I got "free" not found if I don't include machine.e 
include sdl.e 
public constant SDL_VERSION = define_c_type({ 
	C_UINT8, --major 
	C_UINT8, --minor 
	C_UINT8 --patch 
public constant SDL_MAJOR_VERSION = 2, 
export constant xSDL_GetVersion = define_c_proc(sdl,"+SDL_GetVersion",{C_POINTER}) 
public function SDL_GetVersion() 
	atom ver = allocate_struct(SDL_VERSION) 
	sequence res = peek_struct(ver,SDL_VERSION) 
	return res 
end function 
export constant xSDL_GetRevision = define_c_func(sdl,"+SDL_GetRevision",{},C_STRING) 
public function SDL_GetRevision() 
	return c_func(xSDL_GetRevision,{}) 
end function 
export constant xSDL_GetRevisionNumber = define_c_func(sdl,"+SDL_GetRevisionNumber",{},C_INT) 
public function SDL_GetRevisionNumber() 
	return c_func(xSDL_GetRevisionNumber,{}) 
end function
