Registered by Marcin Juszkiewicz

Whiteboard

[rsalveti, 2011-11-10] Shouldn't this be part of the linaro-ubuntu project and targeted for 11.11?
[fboudra, 2011-11-10] re-target to linaro-ubuntu/11.11 to get it visible under Developer Platform status.
[hrw 2011.11.16] gnat/cross is not possible - probably same with gcj - cross gcc is built instead
[dzin 2011-11-17] Please add a headline and acceptance criteria
[dzin 2011-11-23] This is a work list for hrw only, and as such it is moved to the backlog
[dzin 2011-11-29] Moved to trunk
[hrw 2001-12-20] All usable changes were merged. Rest can stay where it is.

Headline:
All changes to gcc packaging got merged back into Debian/Ubuntu gcc packages.

Acceptance:
gcc-4.6, gcc-snapshot and gcc-linaro build natively out of box with minimal set (or none) of patches applied to packaging. gcc-4.6 and gcc-linaro build as cross compiler.

Code present here: https://code.launchpad.net/~hrw/ubuntu/precise/gcc-4.6/cross-fixes
Builds are in my PPA: https://launchpad.net/~hrw/+archive/my-own-packages/
Merge request: https://code.launchpad.net/~hrw/ubuntu/precise/gcc-4.6/cross-fixes/+merge/82269

SOURCE_BUILD_DEP changes needs checks with gnat/gcj
