The "errors" are mostly duplicate symbol warnings, that are part of generating
a shared lib on AIX (in a mostly gcc and xlc independent way), and can be safely
ignored.

The imho most needed effort for AIX would be to switch the TAS stuff from
cs() to fetch_and_or() or a PowerPC assembler or the test_and_set() that is
undocumented/intended for kernel, see discussions from last year.

The fetch_and_or() is a lot faster on multi processor systems but a little
slower on single processor. But cs() is documented as depricated, so ...

I might get round to doing this.
