It would be nice if compilers could do a bit of processing,
determine that printf("string with no formats") can be transformed
into puts -- so that we can get on with the important job of solving
problems, and not have to play games remembering which I/O function
to use today (well, tcputs() is almost what I need, but its 
buffering conflicts with fooprintf() which is implicitly used
by the error printing routine used in module xyzzy).
