The problem is, that the default on AIX is to produce architecture independent
code (arch=COM). Unfortunately not all AIX architectures seem to have these
instructions. With arch=ppc it works (two lines adjusted .globl .tas and .tas:).
My worry is, that the Architecture book sais that the isync is necessary on SMP.
I wonder why that would not also apply to LinuxPPC or Apple.
