--- Comment #3 from Berck Nash <berck.nash at wdc dot com> --- I can see that someone might want to do this, but it certainly doesn't seem like it should be default behavior. I think it's a bit absurd to expect an end user to know the names of every function called by every library function. It seems like, by default, a collision should be reported. Additionally, even if this is a feature, there isn't even check to see if the functions have compatible parameter lists, which can make for some disastrous mistakes...
