Your proposals sound rather dangerous. They would silently break recompiled threaded programs that need the locking and don't use -D__REENTRANT (most people do not seem to use it). I doubt the possible pain from that is worth it for speeding up an basically obsolete interface like putc.
i.e. if someone wants speed they definitely shouldn't use putc()
