Nope. This is a tautology on the trunk.

Since you didn't define an inline version of IsOSSnowLeopardOrLater
here, the definition of IsOSSnowLeopardOrLater()
in mac_util.mm should not be inside an
  #if !defined(BASE_MAC_MAC_UTIL_H_INLINED_GE_10_7)
block.

 inline bool IsOSSnowLeopard() { return false; }
