They try to deal with this by making the library versions of math functions the same as the in-lined ones, except possibly for limiting cases. For example, the paranoia test for the accuracy of pow(x,y) where x is near 1. and y is large shows exactly the same problems either way. Not that it's clearly beneficial for pow() to in-line.
