Hello,
I'm trying to compile my project with my build of clang++, for some reason I get a lot of compile errors.
My main.cpp file:
```
#include <iostream>
int main() {
std::cout << "Hello world!" << std::endl;
return 0;
}
```
If I call clang++ like this:
```
./path/bin/clang++ main.cpp -o main
```
I get this error:
```
In file included from /path/main.cpp:1:
In file included from /usr/local/bin/../include/c++/v1/iostream:37:
In file included from /usr/local/bin/../include/c++/v1/ios:214:

/usr/local/bin/../include/c++/v1/wchar.h:119:15: fatal error: 'wchar.h' file not found
#include_next <wchar.h>
^~~~~~~~~
```
If I call clang and add the headers like this:
```
./path/bin/clang++ main.cpp -o main -I /Library/Developer/CommandLineTools/usr/include/c++/v1/
```
I get this error:
```
In file included from /path/main.cpp:1:

wchar_t* __libcpp_wcspbrk(const wchar_t* __s1, const wchar_t* __s2) {return (wchar_t*)wcspbrk(__s1, __s2);}
^
.........
```
I already try to add other header paths and compile flags like: `-std=c++11` and `-stdlib=libc++` but nothing seems to work...
Thanks!
