Yes, std::nearbyint is specified in C++11, at least according to
http://en.cppreference.com/w/cpp/numeric/math/nearbyint
On the one Ubuntu 10.04 system I have easy access to, I can't install
the build dependencies of linuxcnc, but this translation unit does
compile with "g++-4.4 -std=c++0x" or "g++-4.4 -std=gnu++0x":
#include <cmath>
const auto i = std::nearbyint(3.14);
so either it's some local detail of your system or some additional
compiler flag that LinuxCNC has added. You can see full compiler
commandlines if you run make V=1
The call was added to LinuxCNC recently in the master branch after we
dropped support for 10.04, and so it was never tested on 10.04.
