And in glibc versions in the relevant interval, timer_t was int.  So this 
redirection to a function taking int * is correct; callers of this 
function were compiled against glibc versions at least 2.2 and less than 
2.3.3, and will be passing a pointer to int.

If there's a problem here, you'll need to explain it further.
