Comment(by ryandesign@…):

 Replying to [comment:9 ryandesign@…]:
 > the code was deliberately changed upstream to
 [http://cgit.freedesktop.org/mesa/mesa/commit/?id=930838efcdac04dd0a0c7ee0375364548a0efe8c
 only use PIPE_ATOMIC_GCC_INTRINSIC if GCC 4.1 or greater is found]

 Couple this with the fact that the code was deliberately changed to
 [http://cgit.freedesktop.org/mesa/mesa/commit/?id=7827bc73c79a506937b20ae834c89273bfb92c12
 remove the PIPE_ATOMIC_MUTEX fallback] that had been in place if all else
 failed, with the only explanation that they wanted to "severe [sic] the
 dependency in [sic] OS abstractions from the Gallium interfaces".
