Sorry for the typo.  Yes, it should be sprof.1.

TBH, I don't know either, as I never used sprof(1).

At a minimum, a reply would need the following header fields:

	Cc: <libc-alpha@sourceware.org>
	In-Reply-To: <87mshxxyol.fsf@oldenburg.str.redhat.com>

That should be enough.  Let me know if you need more help.  I've bounced
the whole thread to you so that you have it in your mailbox; that will
make it easier for you to reply.


Have a lovely night!
Alex
