[ Please CC: me on replies, not on questions@ ]

Is this a GCC bug with the -Wconversion flag or am I doing something
wrong?  I know it's just a warning, but it's irritating me more than
that dumb Dan Quayle quote, "if it weren't for that horse, I wouldn't
have spent an extra year in college..."  -sc
