Undefined static function

[Frank Cringle]

Here's a question for all the C language lawyers out there.  What should
a C compiler make of the following:

	static char *tgoto();

	main()
	{
		.....
		if (tgoto(......).....
		.....
	}

In other words, we declare a function to be static, use it, but do not
define it in the source file.  This occurs in libcurses/cr_tty.c (4.2BSD).
The 4.2 compiler happily accepts this and links the 'static' tgoto to a
definition in another source file.  In this case it is what the author
intended, but it should really have been thrown out by the compiler,
methinks.
