Exactly the reason why I like the idea of deprecation messages but also like
being able to disable them. It's not really impossible or unthought of that
it may take a stupidly long amount of time for a vendor to fix their broken
application that depends on a bug of a deprecated library *and* misbehaves
because of a message sent to stderr by the linker.
Having said that, since this is being deprecated in 6.X, which is pretty much
"current" and people aren't really expected to jump on the FreeBSD-current
wagon if they use FreeBSD for production, how many people use libc_r now that
may be bitten by the deprecation messages?
