There is no reason whatever for an Ada compiler to spend any
noticable time on this "make" functionality. Certainly with
GNAT there is no overhead at all from this source that is
noticable.

A minute for the clean build case is not that significant. You
are not doing this kind of
registration each time you compile a unit, so I think it is
probably negligible in practice. In any case this is an artifact
of one particular approach of one particular compiler, nothing
to do with Ada or Ada compilers in general.
