Apologies. I'm travelling and in trying to avoid the mess of top-posted
HTML that would result from using the Android mailer, I was using
SquirrelMail. For reasons I will attempt to establish when I get home,
that results in a line of what *should* have been an RFC822 header,
being visible in the body of the email. Please ignore that.

(And yes, {ns1,www,ftp}.infradead.org is currently AWOL)

I think my observation was more than "not used by the library itself".
It was also (in HEAD) not in an exported header file, and not
documented. And not actually used anywhere outside the FIPS module.

The BIO thing came to mind when fixing other no-stdio failures, with
code that thinks it's OK to fprintf(stderr, …). That code *could*
potentially use BIO_printf(OPENSSL_stderr(), …). Or could just be fixed
not to do that kind of thing at all.
