Hmm. Not with GNAT 5.04a on windows.

Hmm. Maybe you meant 'gnatls -Pfile -v':

Hmm. It doesn't actually use the project file; I get exactly the same
output with a different project file.

The -P option is not shown in 'gnatls -v', nor in the GNAT user guide.
So this is expected, except that it should have reported an error
about "unrecognized option".

GNAT 5.05w doesn't have it either.

So apparently this only outputs the system libraries. Although I have
no idea why 'gnavi\gnatcom' is showing up here. Something in the
Windows registry?


So I still need to implement 'gnatgpr'.

Perhaps I should implement it as a patch to 'gnatls'. However, the
5.04a1 gnatls source does not 'with Prj.*', and the data structures
for storing the lists of things are entirely different from those used
by Prj.*, so it would be a complicated patch. I assume that's why
AdaCore hasn't done it yet :).

Implementing a separate 'gnatgpr' would be much simpler.

Would AdaCore be interested in adopting that code, once I get it
working?
