In this function (used to check the size of a global) there is an initial check for whether the initializer to this function is "definitive." My question is: why do we need this? How does the object's size change if a global's initializer is defined at link time? Thanks, Karl -------------- next part -------------- An HTML attachment was scrubbed... URL:
