           Summary: cmath does not work with clang -std=c++0x or
           Product: libc++
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P

A simple:

#include <cmath>

does not work on mac os x 10.6, with clang -std=c++0x or clang -std=c++93. It
works fine with -std=gnu++0x and -std=gnu++93.

I had assumed that -std=c++0x was the 'natural' extension to get c++0x support.
I can see I should probably be using gnu++0x. That is an unfortunate choice of
naming (but probably clang's fault).
