The question you have to ask yourself is, are these symbols part of the public API? and probably more importantly, where are they defined? I have seen, in the past, many situations where optimization level would influence what symbols are exported or not. And different versions of g++ may optimize things differently. This can, for example, occur with code in header files (which can happen in C++ classes definition). Mike -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
