 Replying to [comment:16 kencu]:
 > You do have a 10.5 PPC machine - you might try it there, as it should
 help there too, I hope.

 I hope that I can start testing on PPC Leopard on Wednesday. Should I
 install and upgrade Clang 3.7, as documented in LibcxxOnOlderSystems, or
 should I start with Clang 3.8?

 Making Hyper Text Transfer Protocol v. 2 work on PPC Leopard is quite
 ambitious, I think…
