You mean NetBSD? I don't know about Linux. NetBSD does not paper over the
lack of 64bit atomics in 32bit ppc userland by default, so: yes.

Unless you can compile the code (there often are #ifdef's for it)
to avoid the 64bit data type that is used atomically here.

Yes, many pkgs in pkgsrc add it as a dependency on i386 and ppc (and
a few more less common architectures).
