Neither do I for the long term. I was seeing this as a temporary
work-around while the larger design issue is getting worked on.
The patch is relatively small and it's easy to get rid of that flag
once it becomes OBE.

Agreed. I'm curious as to what the other maintainers think of this
approach. I will probably use this patch in AdaCore's tree, but
thought that it might be useful to others as well. The complaint
is one part of it which I find to be an issue (they will drown any
other complaint that we might emit), but there there is a small
performance aspect where we skip scanning objfiles that do not need
to be scanned.

Anyway, let's see what the others think. I'll pursue this further
if there is interest.
