Atomic builtin support for IBM Cell

["Johnny Willemsen" <jwillemsen@xxxxxxxxx>]

Hi,

We are looking at using the atomic builtin support, but is there an
optimized version of Atomic builtin available for IBM Cell PPU, or does the
fallback just use a regular lock/unlock?

Is it also true that with GCC 4.4.{2,3} we now have to enable the C++0x
features for using the atomic builtin support? 

Regards,
