The Ada FE does it FWIW: $ cat p.ads pakage P is subtype My_Count is Intger end P; $ gcc -c -gnatq p.ads p.ads:1:01: incorrect spelling of keyword "package" p.ads:2:23: "Intger" is undefined p.ads:2:23: possible misspelling of "Integer" p.ads:2:29: missing ";" $ The checker is in gcc/ada/g-spchge.adb Laurent
