So unfortunately, again the question which comes to mind is what
should happen when a program specifies an undefined behavior?
Persona
Many C++ testsuite execution tests started failing on mainline between 20050627
and 20050630, on platforms including hppa2.0w-hpux, hppa64-hpux and ia64-hpux.
gcc-testresults shows failures also on other platforms such as ia64-linux.

I think there might be an actual bug with this new warning:
In the qsort man page, it says you can use strcmp as the last argument to qsort.
So the types must be compatible, and it also works. However, this fails:
