/* Macros for aggregating results built on the stack into an array, * while maintaining a bound on stack consumption. Use like this: * * check_stack(120); * BEGIN_AGGREGATE_ARRAY(estimated_size_of_final_array) { * for (...) { * ... stuff that produces a value on the stack ... * DO_AGGREGATE_ARRAY(120); * ... * } * } END_AGGREGATE_ARRAY; * * The array is left on top of the stack. */
