[Chicken-hackers] OS X: clang's failing 'make check' w/ 4.8.0rc3 tarball

[Derrell Piper]

Hi,

The 4.8.0rc3 tarball built with clang is failing 'make check' on OS X
using the command_line_tools_for_xcode_os_x_mountain_lion_aug_2012.dmg
tools (from the Apple Developer Downloads section).  gcc's fine and
clang builds okay, it's only the 'make check' that's failing.

build commands used:
  make PLATFORM=macosx ARCH=x86-64
  make PLATFORM=macosx ARCH=x86-64 C_COMPILER=clang

gcc says:
  fluffy584% gcc --version
  i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) 
(LLVM build 2336.11.00)

Here's the failing part:
