[Nix-dev] Help needed: PPL on Darwin and Cygwin

[Ludovic Courtès]

Hello,

The Parma Polyhedra Library (PPL) fails to build on Darwin and Cygwin:

  http://hydra.nixos.org/job/nixpkgs/trunk/ppl/all

For Darwin, it appears to be a gcc-apple issue (not surprisingly).  On
Cygwin, we hit a GCC internal error.

PPL is a dependency of GCC 4.4.  While it's optional, not using it would
deprive us from the shiny Graphite optimization framework
(http://gcc.gnu.org/wiki/Graphite).  Thus, I think it's important to
have it on Darwin and Cygwin, if we are serious about these platforms.

Would Darwin/Cygwin-savvy people like to help?

Thanks,
Ludo'.
