Strange.  I just rebuilt an Emacs snapshot on FreeBSD/amd64, but I don't
see incomplete type dereferencing errors.

How are you checking out your copy?

Does the environment contain any special CFLAGS when you run ./configure?

This indicates a local environment problem, IMHO.  Can you send the
output of:

    $ env | sort

right before you run `./configure'?

Hmmm, not sure.  I'm using gcc-3.4.4 here; the one that comes with
FreeBSD-CURRENT as the base-system compiler & toolchain.

No, things are pretty stable here.  I've been building Emacs CVS
snapshot since last October on FreeBSD 7.0-CURRENT.  The only problem
that I have to track down is why enabling HAVE_POSIX_MEMALIGN in
src/config.h crashes at bootstrap time.

Without HAVE_POSIX_MEMALIGN, current Emacs builds are stable enough for
months in a row now.

It's probably a local environment option that's causing all this.  We'll
find out what it is and fix it -- don't worry :)
