* ASORT_KEY_TYPE [*] data type of a single array entry key
* ASORT_ELT(i) returns the key of i-th element; if this macro is not
* defined, the function gets a pointer to an array to be sorted
- * ASORT_LT(x,y) x < y for ASORT_TYPE (default: "x<y")
+ * ASORT_LT(x,y) x < y for ASORT_KEY_TYPE (default: "x<y")
* ASORT_SWAP(i,j) swap i-th and j-th element (default: assume _ELT
* is an l-value and swap just the keys)
* ASORT_THRESHOLD threshold for switching between quicksort and insertsort
