I did not have trouble (on i386):

FreeBSD g1-227.catwhisker.org 9.0-STABLE FreeBSD 9.0-STABLE #195 237440M: Fri Jun 22 05:22:20 PDT 2012     [hidden email]:/usr/obj/usr/src/sys/CANARY  i386

Peace,

There seems to be something wrong with your cdefs.h file.  Please check
your copy, which should be in:

/usr/home/bketchum/kernels/stable-9/sys/sys/cdefs.h

Alternatively, try running the failing command line with -save-temps,
and upload the resulting bt_close.i somewhere (or attach it, but
compress it first, please).
