Does the NASM code do the right thing with regard to CPU model detection?  It sounds like
there may be dependencies on instructions that may not be on all processors for which Apache
OpenOffice is supported.  I am thinking in particular about processors on which Windows XP
will run but Windows 7 and later will not because of hardware protection requirements and,
I suspect, extended instruction sets.
