 ARCHITECTURES SUPPORTED
 -----------------------
 
-Currently, x86 (i386, i486, i586, i686), x86 64, PowerPC 32/64 and S390 are
-supported. The current use of sys_futex() makes it Linux-dependent, although
-this portability limitation might go away in a near future by using the pthread
-cond vars.
+Currently, x86 (i386, i486, i586, i686), x86 64-bit, PowerPC 32/64, S390 and
+S390x are supported. Only tested on Linux so far, but should theoretically work
+on other operating systems.
