IIRC I have already asked a similar question about atan2, erf, ...
which don't appear in the std namespace on darwin.
You should check whether darwin by chance uses by default c_std instead
of c_global. The former doesn't provide C++11 facilities. If, on the
other hand, it uses c_global, it means _GLIBCXX_USE_C99_MATH_TR1 is
undefined because a configure test fails on that specific darwin release
you are using. But the last time I checked, modern darwin defined
_GLIBCXX_USE_C99_MATH_TR1, no problems.
Anyway, about the cstdlib issue the below makes available the new
functions in c_std/cstdlib too, and I'm going to commit it, it's close
to what Jason originally committed. But, as I said already we don't
normally provide C++11 functions in c_std, Benjamin may want to review
what we are doing in c_std vs c_global, he designed the split.
