Epoch 4.2 compiled with cc, running under SunOS 4.1.2.

Position the buffer in the window so that the last line of the buffer
coincides with the last line of the window (i.e. so point-max is next
to the minibuffer, but still visible).

Then evaluate:

	(goto-char (point-max))
	(pos-visible-in-window-p (point-max))

pos-visible-in-window-p will return `nil', when it should return `t'.

Let me guess... using variable height fonts in your minibuffer?

I have posted a similar bug report twice earlier.

Using Epoch 4.2 with a separate minibuffer and no variable height fonts:
If the last line of the buffer is at the last line of the window, then
(pos-visible-in-window-p (point-max))
will return `nil' instead of `t'.

The same bug has appeared in earlier versions of Epoch but not in Emacs.
