             Bug #: 55795
           Summary: GNAT User Guide mentions features-ada12; no such file
                    exists
    Classification: Unclassified
           Product: gcc
           Version: 4.6.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: prosfilaes@gmail.com


The GNAT User Guide mentions features-ada12. (I have 4.6.3 installed, but this
file is not present in the source distributions for 4.7.2 or 4.8-20121216,
either.) This is rather frustrating, as there doesn't seem to be any place
where what Ada 2012 features are supported are listed; formally speaking,
that's an enhancement request, whereas the missing file is an error. (And not a
completely trivial one, as it causes users to go on a wild goose chase for a
file that doesn't exist.
https://groups.google.com/forum/#!msg/comp.lang.ada/pR8t6YJI4JI/ELaifpbkUDIJ
shows that I'm not the first to be frustrated by this problem.)
