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-, 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[14] 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
    • 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.

    • Requires rebuild of packages using the changed ABI.
  • 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.
