It sounds like you are using the gcc-headers, which causes troubles within
clang.
Try using clangs own headers by passing the "-resources <path>"-parameter to
clang.
To see the correct resources-path, take your cpp-file and call
clang -### <yourcppfile>
on it - you will see the default arguments that clang would use to compile
the file, the
resources-parameter should also be included.
