Changes between Initial Version and Version 1 of Ticket #50481, comment 12

initial	v1

3		I suspect the patch in block #21 above probably should be broadened out to apply to all systems, although the lack of it might only be a deal-breaker at specific times. I'm thinking this is probably going to relieve that weird "-lobjc" bit I had to add in the 10.5 and 10.6 libc++ block fix some months back, and it's clearly needed on 10.7 too.

5	5	Then it's just a matter of blacklisting older clangs when building against libc++ -- although it seems older clangs can build qt4-mac against libstdc++, newer clangs appear to be needed for building against libc++ if I'm reading the tea leaves correctly here.
