Subject: [svn-r8886] Purpose: bug fix.

Description:
The previous patch of -D__GNUC__ was causing failure in the
newer compiler.  The previous failure could not be repeated
any more.  So, removed it.

Platforms tested:
Tested only in TG-NCSA since the change affects only the ia64 platform.

Misc. update:
