This is my supposition. There have been many messages to this list
which clearly say that advanced gcc options (like advanced
optmisations) are a bad idea for CFLAGS defaults in make.conf
because they can prevent world/kernel from rebuilding properly. So,
playing spot-the-difference between your compile line which fails,
and my last one which succeeded...
Yours:
cc -E -O2 -fno-strict-aliasing -pipe -I. -I/usr/src/bin/csh
-I/usr/src/bin/csh/../../contrib/tcsh -D_PATH_TCSHELL='"/bin/csh"'...
Mine:
cc -E -O -pipe -I. -I/usr/src/bin/csh
-I/usr/src/bin/csh/../../contrib/tcsh -D_PATH_TCSHELL='"/bin/csh"'...
You'll see that your has -O2 and -fno-strict-aliasing while mine has
just -O. So the first thing I would do is to try fixing CFLAGS in
make.conf to get rid of "-fno-strict-aliasing" and change "-O2" to
"-O". I can't say whether one, both or neither is actually wrong,
but mine worked and yours didn't, so at least one of them is a good
potential source for the problem.
Let us know if it helps. Someone out there undoubdetdly knows which
options are safe to add here, and may even be able to say where they
are documented.

PS You neglected to mention which version of FreeBSD you were running.
My compile line is from 5.4.
Thank you Alex for a very interesting reply.
My bad for not mentioning FreeBSD 5.4-STABLE: Wed Sep 21 01:34:15 CEST 2005
All the best,
Vaaf
