[Vm-dev] extern function with definition

[Ben Coman]

Here is something I don't comprehend, a function declared extern but also
with its definition provided.  Is there anything strange about that
arrangement?

extern int sqAskSecurityYesNoQuestion(const char *question)
{
    return MessageBoxA(stWindow, question, "Squeak Security Alert",
MB_YESNO | MB_ICONSTOP) == IDYES;
}
