Ran repoman and fixed problems.
Unfortunately it will error out whenever we mark any package stable, that has GDC use flags that could pull in any unstable version of gcc, which would be all of them.
That's the downside of "a package can only be marked stable, when all its dependencies are".
Completed repoman fixes.
Added dmd-2.066.
Added GtkD-2.3.2.
Added GDC for D 2.065, based on GCC 4.8.3.
Merge branch 'master' of https://github.com/gentoo/dlang

Fix to GDC ebuilds. GCC_FILESDIR is now globally defined.
