[cfe-dev] Errors compiling libc++

[Ron Santos]

Folks,
I just checked out libc++ revision 131708 a few minutes and tried to build
with clang 3.0.

$ clang++ -v
clang version 3.0 (trunk 131637)
Target: x86_64-apple-darwin10.7.0
Thread model: posix


I downloaded the helper libs and exported TRIPLE.  I get the errors below.
 Am I doing something wrong?  Is this expected?  Thanks for your help.  I
want to play around with some C++0x features so I decided to use clang and
libc++.
