------- Comment #3 from pinskia at gcc dot gnu dot org 2007-03-29 15:15 ------- Plain inline without any thing which says static or extern in C99 is the same as what GNU-C90 considers as their "extern inline" and not what C99 considers as "extern inline". If you add a prototype that says extern, it will just work.
