I think so.  Speed.  I predict that there are cases where using -frepo
will yield smaller .o files, and will take less time to generate them
and less time to link them.

Though I admit I have never benchmarked it.  Also, this is probably
only an issue for large projects (it takes an hour to link, type
ones).
