 // Defines how `x___alloc()` functions should exit. `___VXGG___XALLOC_EXIT_ON_ERROR___ > 0` calls `error()`, and thus functions
 // registered with `atexit()` and `on_exit()`. `___VXGG___XALLOC_EXIT_ON_ERROR___ <= 0` calls `abort()` on error. `x___alloc()` 
 // type functions will ALWAYS 'abort', doing otherwise defeats the purpose of the function type
