small patch for objdump

small patch for objdump

[Philip Blundell]

I just found this change in my tree.  I made it some months ago to fix a 
problem with addresses above 0x80000000 being reported incorrectly when 
disassembling code.  Although I haven't tested versions later than the 2.9.1
release it looks like the problem is still there; would someone like to 
take a look?  Thanks.

	* objdump.c (disassemble_bytes): Make address variables unsigned
	to avoid problems when disassembling code at high-bit-set
	addresses.

I checked, and you are right, the code was still using signed
addresses.  (Of course some processors do have signed address spaces,
but they are in the minority).  So, I have applied your patch.
