I think Juergen had already implemented this.  Could you check your
patch against the one posted in the following message?

From: Juergen Lock <nox@jelal.north.de>
Subject: Re: MiNTlib (I think I'm on pl43): Bug in sprintf().
Message-Id: <9407172345.AA00280@jelal.north.de>

biosfs.c,pipefs.c,tty.c:
        add readb+writeb for ptys (for the slave->master pipe),
        use memcpy for all pipes
        really buffer 4K not 4K - 1 byte so the copies are aligned more often
