fpmake does not know about unit dependencies, so it compiles all units once. The compiler may however already compile a unit earlier on because it's required by another unit. At least the trunk version of fpmake supports automatically generating a "build unit" that simply adds all the to be compiled units to the uses clause. It then compiles only this build unit, so that every unit will be compiled only once.
