Hmmm, tu n'as pas cherché très bien à mon avis.

Comme tu vois, ça se fait en 2 étapes. D'abord, on met le type du programme en fonction des switches (dans main.c) et/ou des exports à noms réservés (dans special.c), puis on met le type d'exportation en fonction du type du programme (dans export/export.c).
