But automake doesn't want us to do that: users' settings (in this case CFLAGS)
are supposed to override all--and so they come last on the compile line.

To do it we'd have to override CFLAGS (which we're not supposed to do).
Maybe Jeroen's suggestion from comment 7 is the way to go--even if our code can
handle it?
