	 "_doprnt(fmt, &args, stderr);		/* this is the good line */"

On the contrary, this is the bad, unportable, implementation-dependent
line.  If you search chapter 3 of the Unix manual, you will not find
an entry for _doprnt.  This is because it is a detail of the implementation,
not a guaranteed feature of the library.  There are Unixes that don't have
such a function.  Incidentally, the technique of passing _doprnt a whole
argument list by passing it the address of one argument is also machine-
dependent and unportable.
