+Description: workaround for Mac OS X 10.5
+ The Mac OS X 10.5 SDK requires the second argument of FD_ISSET to be
+ writeable, although it does only access the data. Given that we have a
+ const pointer for a const struct, copy and pass that.
+ .
+ Note that this is merely a workaround for OS X 10.5, as 10.6 and later
+ define the second argument of FD_ISSET as const struct const *foo, too.
+ .
+ It is safe, as data is accessed read-only by FD_ISSET, even on 10.5.
+Forward: pending
