	Here is the output from the new fdisk examining a disk where the
	second partition is extended and contains 
		0: 128MB Linux ext2fs
		1: 100MB Linux swap
		2: 3.75GB MSDOS

>How-To-Repeat:
	I don't think this is an error with my disk partitioning.
	It looks ok from both Linux and Windows (for what that's worth).

>Fix:
	Sorry...
