Sure, but don't the GNU coding standards disagree with POSIX here? If we 
follow the GNU coding standards with respect to stdout, then we need a 
POSIXLY_CORRECT check.

Or are you suggesting that we disregard the coding standards and follow 
POSIX instead? That would be a reasonable suggestion but we might want 
to ask RMS about it.

While I'm bikeshedding :-), one other thought is that if POSIXLY_CORRECT 
is not set we could also be compatible with FreeBSD, and output a bell 
before the first page if -f is specified but -p is not. I suspect that 
this is a more-useful approach (and could well be what System V did, and 
we've merely exposed a bug in POSIX here).
