The issue have been resolved with 0.6.2, thanks!
I would suggest to claim that 0.6.0 and 0.6.1 releases are broken for
the powerpc architecture.
Or applying:
http://git.lttng.org/?p=userspace-rcu.git;a=patch;h=e6e5957d053147ab7d31...

To 0.6.0 and 0.6.1, this could be described in the documentation.

Hi,
I am unable to build for powerpc.
I run configure with theses parameters:

This is rather confusing since urcu-call-rcu-impl.h does include the
correct header file were uatomic_or exists(uatomic/generic.h).
Is there a specific macro that has to be included in CFLAGS? like -DPPC
or -D__PPC__ ?
