Hi Nicolas,

Apple ships its own modified version of GCC and some of the changes they
make are mighty bone-headed.  If you google for the terms

  Undefined symbols: printf$LDBLStub

you'll see that number of other folks have encountered this problem or
similar ones.  It has something to do with Xcode and I think it can be
disabled with a compiler switch or an environment variable such as:

  export MACOSX_DEVELOPMENT_TARGET=10.4

or maybe an additional

  -lSystemStubs

or something.  I don't have access to a Mac right now and don't have
time to fight with it.  Keep google-ing and I'm sure you can find a
better answer.

Ed
