BTW, what kind of benefit are we looking at?
Is the resulting executable smaller?  If so by how much?
Is it faster?  If so by how much?
Is the compilation quicker?

I understand this depends on other optimization options and the machine
on which you test it, but does someone have at least some vague
measurements to get an idea if the effort is worthwhile or not?
