The attached patch removes '-flat_namespace' and consistently uses
'-undefined dynamic_lookup'. It also restricts the changes to just the
darwin config hints file, which seems like a more appropriate place. It
resolves all the test failures related to undefined symbols on OS X.
(t/src/intlist.t is still failing the 4th test, but it fails the same
way on Linux when I unTODO it.) It also runs 'make perl6' without errors.
If you're running some flavor of OS X, please test this patch. (Let me
know if you're running a version before 10.3. It was released October
2003, which is significantly before our "versions released in the past 2
years" cutoff of support for the 1.0 release of Parrot.)
I've wanted to get rid of the '-flat_namespace' hack for a long time now.
