Diff between fedora and upstream gcc/ada folders

Does Gnat GPL really install all of those files in its adainclude directory, or did you compare the API of Libgnat against the complete combined sources of Gnat and Libgnat?

GPRbuild 2010 seemed to build fine. If GPRbuild 2011 requires new features in Gnat, then perhaps Fedora should just stick to GPRbuild 2010 until those features make their way into a GCC release?

ASIS is a special case. I hear it needs to be tightly synchronized with Gnat, so it will probably take some effort to package. I doubt that the solution is as simple as dropping a bunch of files in the adainclude directory. I've been meaning to study how Ludovic solves that in Debian.

Please see /lib/gnat/gnat_util.gpr of Gnat-GPL (Adacore) installation.

Yes, It contain includes from __GNAT-GPL__ (not from GCC-GNAT). GNAT-GPL-2911 contains parts of SPARK (for example). Please read README file for gprbuild-{2910,2011}

I'm using GELA for qtada. ASIS needs to be  tightly synchronized with Gnat, so GCC-GNAT must bring sources as well as any Ada programs in -devel package.

We are shipping whatever upstream GCC-GNAT decided that should be installed.

It's not true we have bunch of "cp" operations in specfile already, for example:
cp -a ../gcc/jit/libgccjit*.h %{buildroot}%{_prefix}/include/ and we ship something different from upstream gcc-gnat even ( https://bugzilla.redhat.com/show_bug.cgi?id=1211957 )

The idea is to introduce libgnat-source package to ship content of gcc/ada. This package should be used only in BuildRequirements of gprbuild (and maybe ASIS) packages. Like we have in ocaml-source for example. Actually gprbuild uses built-in gnat-sources which are gcc-4 branch and broken with gcc-5.

This bug is currently assigned to an unsupported release. If you think this bug is still valid and should remain open, please re-assign it to a supported release (F22, F23) or to rawhide.

Bugs which will be assigned to an unsupported release are going to be closed as EOL (End Of Life) on January 26th, 2016.

This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
