I had the same problem when trying to initially compiler nix-0.12pre12824 on
a debian stable system. The problem is that limits.h has #ifdef's around
the ULLONG_MAX definition that enable it only for standard C99 but not for
C++. This can be worked around in nix by using the proper C++ idiom, i.e.
including <limits> (no ".h") and replacing ULLONG_MAX with
std::numeric_limits<unsigned long long>::max().
