Unfortunately this example cannot be compiled with gcc-mp-4.5 because
of this bug http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44981 . That
is why I try to use unreleased 4.6 version where this bug is fixed.
4.5 version is almost unusable for macosx specific code compilation.
BTW does it make sense to backport the fix to 4.5?
