xcode: error: no matching 'operator new' for non-allocating placement new

[evoskuil]

xcode only: error: no matching 'operator new' function for non-allocating placement new expression; include <new>

Related bugs in llvm/clang are documented. The error states that include <new> is required, yet including this as the very first in define.hpp does not resolve.

Worked around this by implementing own polymorphic allocator and memory resource (for other reasons).
