So far only i386, ia64, and x86_64 define these in posix_opt.h. Is these just missing #ifdef or do I need to enable something for powerpc. If so is there a pointer to a description of this feature.

On i?86/x86_64/ia64 the option is sometimes supported (so #define _POSIX_CPUTIME 0 is correct), while on ppc/ppc64/s390/s390x etc. we don't define it at all. But 1) is almost like 3) when we have the headers/data types/functions, so either we can #define these to 0 on all Linux platforms and use some other (not exported) macro to tell posix-timer.h, timer_*.c etc. whether they should attempt something or not (this would have 2 advantages, the bigger that we could unify all the linuxthreads and all the nptl posix_opt.h headers, but also that e.g. we could decide in the future to use a tick register say on ppc* on hardware that has it (do I remember well that there is something like that on some ppc's?) usable without the need to recompile apps to use it, or we can #define it to -1 to say that it is really not supported.

Well, upon closer inspection timer_create (the userland one) returns ENOTSUP whenever it sees CPU timer clocks (which is something that should be done whenever those CPU timer constants are in the headers, so defined _POSIX_*CPUTIME && _POSIX_*CPUTIME >= 0 is the right check here), but then later on has code to somehow handle it (but it can't work correctly, as the clocks are done in different thread).
