I put in the syntax fix.  The outcome of this test is actually only used on
i?86 (in sysdeps/i386/sysdep.h).  Unless an actual need for it is being
introduced, I would prefer, rather than kludging it up for general use, to
just stuff it into sysdeps/i386/configure.in instead so it won't even run
on ia64.


Thanks,
