work in progress patch to suppress unwind epilogues on Darwin
There was a change in gcc unwinding during 4.5 which is incompatible with the
system unwinders on Darwin 9 (and incompatible with the unwind compacter on
Darwin 10). Specifically we now emit function epilogues.
This is an unreviewed, unapproved, "work in progress" patch ; ergo, it has a
health warning that it might not be acceptable to the maintainers, even if it
works (which I think it does).
If this solves your problem then I think we should alter the description &c.
accordingly.
If it doesn't then, as Mike says, we'll need a reduced test-case to work on.
