commit    e910bd2dfee154c2b010befac4f9b28bbc46003a
Author:   Heikki Linnakangas <heikki.linnakangas@iki.fi>
Date:     Wed Apr 13 08:43:22 2011 +0000
First released in: 9.1.0, 8.2.21, 8.3.15, 8.4.8, 9.0.4

    On IA64 architecture, we check the depth of the register stack in addition
    to the regular stack. The code to do that is platform and compiler specific,
    add support for the HP-UX native compiler.
