>How-To-Repeat:
	Run a fdisk built recently - eveything is "unknown" type.
	NOTE: The machine in question has not been "checked" since Nov. 10,
	so it is likely the changes of Nov. 12 which cause the problem.
>Fix:
	don't know; would guess a "typo" or such in the recent changes.
	NOTE: "fdisk -l" still works, so nothing seems removed, just
	broken.  The function which "fails" is "get_type()" if the file
	/usr/src/sbin/fdisk/fdisk.c at line 2484 when called from line 626
	in version 1.85 of the file.  In particular "bsearch" and "check_type"
	never seem to find the correct partition type (i.e. "check_type" is
	always called with the first list item, never actually searching the
	list).
