	* gdbtypes.h: Create BASE_PTR_CONVERSION_BADNESS.
	* gdbtypes.c (rank_one_type): Move type comparison code out of here
	to...
	(types_equal): ...here. And changed it as follows:
	Outside of typedefs type must be of the same TYPE_CODE.
	When compairing two pointers or references they are equal if their
	targets are equal.
	Correct pointer conversions.
