CGAL users discussion list

bonjour,
j'utilise depuis quelques temps cgal sous linux et sous windows/mvs. Comme je 
dois porter une application Qt4 sous windows, je dois utiliser mingw32 pour 
compiler mon projet. La compilation se réalise correctement mais lors du 
'linkage', il me manque 3 fonctions définies dans assertions.cpp :

assertion_fail
precondition_fail
postcondition_fail

L'erreur me dit que ces 3 fonctions ne sont pas dans le libCGAL.a, ou alors 
il ne les trouve pas.
Serait-il possible de m'orienté dans mes recherches ?

merci.
Julien.

L'erreur (à la fin):
