commit    f16907b98b6ff906e4d0a9f54da07535379968dc
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.
