After applying your patch on Mageia 2 and invoking llvm's configure:

Using clang 3.0 I get:

"checking whether clang works... no
configure: error: Selected compiler could not find or parse C++ standard
library headers.  Rerun with CC=c-compiler CXX=c++-compiler ./configure ..."

Using gcc, there is no error.

After applying your patch on Fedora 17 and invoking llvm's configure:

Using clang 3.0 I get:

"checking whether clang works... no
configure: error: Selected compiler could not find or parse C++ standard 
library headers.  Rerun with CC=c-compiler CXX=c++-compiler ./configure ..."

Using gcc, there is no error.

After applying your patch on Suse 12.2 and invoking llvm's configure:

Using clang 3.1, which has previously worked, there is no error.

So it looks to me, based on my tests, that your patch is successful. I 
look forward to this update in llvm on subversion. Thanks for your help 
on this matter. I will report the broken clang binary installation to 
Mageia 2 and Fedora 17.
