The callee copies ABI used for 32-bit hppa causes no end of optimization
issues and problems with
OpenMP. The hppa target is only in Debian unstable and gentoo. In both
cases, packages are
rebuilt often. So, Helge and I decided that it was better to break the
ABI and accept whatever
problems that result from the switch.
Committed to trunk.
