            Bug ID: 21098
           Summary: clang++ 3.5 Uncorrectly set paths searched for
                    includes - bits/c++config.h not found
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Driver
          Assignee: unassignedclangbugs at nondot.org

Using branch release_35 from llvm and clang on Ubuntu I cannot compile sample
program because of bits/c++config.h file not found.

Procedure to replicate the bug:
svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
cd llvm
svn switch ^/llvm/branches/release_35
cd tools/
svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
cd clang
svn switch ^/cfe/branches/release_35
cd ../../../
mkdir build
cd build
../llvm/configure  --enable-cxx11 --enable-optimized --enable-assertions
--with-optimize-option=-O2
make -j8
cd ..
echo '#include <string>' > bug.cpp
echo 'int main() { return 0; }' >> bug.cpp
build/Release+Asserts/bin/clang++ bug.cpp

Expected result: program is compiled correctly.

Achieved result:
In file included from bug.cpp:1:
/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../include/c++/4.8/string:38:10:
fatal error: 
      'bits/c++config.h' file not found
#include <bits/c++config.h>
         ^
1 error generated.

I believe the problem is in the commit r216531 in clang (please note r216572
depends on r216531). After reverting changes made to file
lib/Drivers/ToolChains.{cpp,h} from those commits, the example code can be
compiled successfully.
