commit    4f5ed3a1cd43598745c1bc9448ba8d331d3aa5fa
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.
