But the extrapolation is invalid.  gcc does a lot of loading of resources on
and off the disk, running external programs, etc.  Much of the time that it
takes for a small program are taken up by this overhead.

The overhead is a "fixed cost," though; it is constant.  It becomes
insignificant when your project is big enough.
