initialisation des classes membres d'une classe

Bonjour!
voici ce que me dit mon compilateur:

Citation:

/home/.../CEchiquier.h||In constructor ‘CEchiquier::CEchiquier()’:|
/home/.../CEchiquier.h|27|attention : ‘CEchiquier::m_h8’ will be initialized after|
/home/.../CEchiquier.h|20|attention : ‘CEventblanc CEchiquier::m_b1’|
/home/.../CEchiquier.cc|4|attention : when initialized here|
||=== Build finished: 3 errors, 0 warnings ===|

Ces erreurs ne m'empêchent pas de lancer mon programme qui semble fonctionner comme je l'attend. Pourtant, j'aimerais éviter ces messages.
Voici le code de la classe en question:

Y-a-t-il une autre methode pour initialiser les membres?
