As soon posted, as soon solved.

I was just confused by a second utility program (a C one) built by the  =

same GPR file, with something like `for Main use ("app1", "app2");`.  =

That's solved now, I removed the second program, so that its own main  =

entry point does not get unfortunately used.

By the way, only `-n` is required here. This works with the combination =
of  =

`-n` and `-z` together, but that's not the purpose of `-z`, as if it wor=
ks  =

the two are combined, that's just the `-n` option defeating the `-z`  =

option, which should not be used for the purpose of having an external  =

main entry point.
