Subject: [PATCH] 	* dwarf2dbg.c: Change bfd_vma to addressT and
 bfd_signed_vma to 	offsetT. 	(out_set_addr): Don't use
 BYTES_PER_ADDRESS.  Instead, get the 	value from the output file
 architecture. 	(dwarf2_gen_line_info): Ifdef BFD_ASSEMBLER specific code. 
 * dwarf2dbg.h: Change bfd_vma to addressT.
