I believe Perl used to use the native C library's qsort routine, but now has
its own routine due to the poor behaviour of many "native" qsort
implementation on pathological comparison functions (that don't return the
same result given the same inputs).

However, note that "native C library" ne "glibc" in all cases. It might an
older libc, or something by Microsoft or Borland or Zortech or whomever.

Cheers,
Philip
