	bfd            : ChangeLog reloc.c 

Log message:
	Extend the allowed bitfield range (ie. that for which
	complain_overflow_bitfield doesn't complain) from -2**(n-1)..2**n-1 to
	-2**n..2**n.  This might mean that some reloc overflows are no longer
	caught, but it solves the address wrap problem for 16-bit relocs
	nicely.  In any case, ports that rely on complain_overflow_bitfield
	for reloc overflow checking were not getting a very good check
	previously.  A bitfield range in a machine instruction is typically
	either the signed or unsigned n bit numbers, not the overlap of these
	two ranges.
