* qsort.c: standard quicksort algorithm
*
* Modifications from vanilla NetBSD source:
* Add do ... while() macro fix
* Remove __inline, _DIAGASSERTs, __P
* Remove ill-considered "swap_cnt" switch to insertion sort,
* in favor of a simple check for presorted input.
*
* CAUTION: if you change this file, see also qsort_arg.c, gen_qsort_tuple.pl
*
* src/port/qsort.c
