// Bison seems to have difficulty growing the parser stack when using C++ with
// a custom location type. This undocumented macro tells Bison that our
// location type is "trivially copyable" in C++-ese, so it is safe to use the
// same memcpy macro it uses to grow the stack that it uses with its own
// default location type. Without this, we get "error: memory exhausted" when
// parsing some large Nix files. Our other options are to increase the initial
// stack size (200 by default) to be as large as we ever want to support (so
// that growing the stack is unnecessary), or redefine the stack-relocation
// macro ourselves (which is also undocumented).
