Karl et al.,

The background on this config.guess issue is here:

I'll let Mojca talk about the 64-bit issue if she wants. I'll note that
as of Mac OS X 10.7, support for 32-bit processors has been dropped, so
we're guaranteed a x86_64 kernel (although the compiler can still
generate 32-bit binaries).

The issue is that invoking cc on Mac OS X 10.9 causes a graphical alert
to be displayed, which tells the user to install Xcode (dev tools). This
is unexpected for many MacTeX users.

Under normal conditions for config.guess usage (i.e., compiling software
as part of autoconf) this is probably desirable and even convenient. The
only workaround I see would be to avoid using cc entirely on OS X 10.9
and presumably later versions.
