I guess what I object to here is the idea that tools like gnatmake or Ant
indicate a problem at all.

GNAT's library model lives on a different place on the tradeoff curve as
compared to the other Ada vendors. It allows some problems to be avoided at
the expense of suffering from other possible problems that the other Ada
vendors do not.

It is also pretty simple.

So, if one considers gnatmake to be an essential part of the GNAT build
system, then my view is that this how the build dependency problem is solved
for GNAT. 

There is no problem with the implementation as such.
