[PATCH] Use compatibility regex library also on AIX

[Johannes Sixt <j.sixt@viscovery.net>]

This augments 3632cfc24 (Use compatibility regex library on Darwin,
2008-09-07), which already carries a "Tested-by" statement for AIX,
but that test was actually done with this patch included.

Here it is. Disclaimer: This patch submission was hand-crafted. ;)
