It was backported to 2.2-stable ages ago... It is rev 1.7 in 3.0-current
and 1.3.4.1 in 2.2.

Be careful.. If it's the version I'm thinking of, I wouldn't be so quick
to do this. One version I've seen around scans for % fields in the string
to estimate the size and does a malloc and vsprintf. This scares the hell

You can get the current 2.2 version and it should just drop into both 2.1
.x and 2.2.[12].
