I think you're assuming there's some specific code to deal the uppercase form, but it just looks for a close match and suggests it. You get the same for other mispellings: gcc: error: unrecognized command-line option ‘-std=p99’; did you mean ‘-std=c99’? gcc: error: unrecognized command-line option ‘-std=T99’; did you mean ‘-std=c99’?
