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: unassig...@gcc.gnu.org ReportedBy: prosfil...@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.)
