| * Change the long double data type on sparc and powerpc from 64bit to 128bit.
* Requires rebuild of packages exposing "long double" in the API of the package (Ldbl128Main, Ldbl128Universe)
| * Change the long double data type on sparc and powerpc from 64bit to 128bit, essential for glibc-2.4
* Requires rebuild of packages exposing "long double" in the API of the package (Ldbl128Main, Ldbl128Universe); we don't require renaming of the library packages, only supporting dist-upgrades from edgy to feisty.

Launchpad entry: none yet
Packages affected: gcc*, gcj*, glibc, binutils
Define features and versions to use in feisty, demoting/removing old compiler versions; use the upstream versions which are available now.
- glibc: 2.5, as available in feisty, using DT_GNU_HASH support.
- binutils-126.96.36.199.6, as available in feisty, using DT_GNU_HASH support.
- gcc: 4.1, as available in feisty; upgrade to the 4.1.2 release or the 4.1.2 branch until UVF.
- C++: backport the C++ visibility changes to 4.1; needs changes in packages to use this feature (i.e. KDE).
- gcj: Decide before UVF about gcj-4.2 or gcj-4.1, depending on the upstream 4.2 release date. If 4.2 is released/in prerelease state, the java packages and libgcc will be built from the gcj-4.2 sources.
- Change the long double data type on sparc and powerpc from 64bit to 128bit, essential for glibc-2.4
- Demote gcc-3.4 from main; requires dropping g77 from main, using gfortran to satisfy build-dependencies in main (fftw3, lapack3, python-numarray, python-numeric, refblas3) or using packages which can be built using gfortran.
