IBM VAC++ 3.08 (made in about 1995) is imho most stable IBM compiler
for OS/2. VAC 3.65 and 4.0 both support it.
The last stable version of EMX (GNU compiler and utils) for OS/2
contain GCC 2.8.1

As far as I understood all those are different ways to hell ;-)

First, we don't use <iostreams>, I hope.
Second, I meant the qsort funstion and it's argument function.
