Merged-by: Michael Niedermayer <michaelni@gmx.at>

Shared libraries and the IBM compiler are currently not supported.
"--arch=ppc" has to be passed to configure, uname is not compatible.

The aix header math.h defines "extern int class()" for C.

The aix header sys/mstsave.h defines FRAMESIZE as _FRAMESIZE.

The aix header sys/thread.h contains a definition for thread_init().

The aix header sys/m_param.h defines HZ as _HZ.

The aix assembler does not support local lables.
