Port: libunwind-headers added; ld64 removed

libunwind-headers need to be updated for better Tiger support.

That bug was opened October 2013, though I see there was some activity from you today. Do we think this is an easy problem to fix soon? As it stands, no ports can be built on Tiger, since all ports on Tiger depend on apple-gcc42 which depends on the now unbuildable ld64.

Yeah, that's just a reminder for me to send my changes upstream at that location when I make them, so others outside of MacPorts can benefit.

Yes. It should be fairly easy.

We just want to change from using Availability.h to AvailabilityMacros.h on Tiger.

This should unblock you:

  1. Update to r131424
  2. Update config.h installed by libunwind-headers to change the '#if APPLE' to '#if APPLE && !defined(USE_MACPORTS_LIBUNWIND)' in config.h

I'm working on a better solution for this.
