If you see one, then I accept one was there. I didn't see one, and a
full make distclean and re-compile doesn't show a compiler warning for
that either. So I guess I'm doing something wrong, on this platform:

I'm using Ubuntu 10.04 LTS, with commands for development:
./configure --enable-cassert --enable-depend --enable-debug
make -j4

The compile output has been somewhat dirty of late, with various
messages, which if nothing else indicated to me that fairly strict
warnings were enabled... though I guess not.
