+ * config/alphaosf.mh (HDEFINES): Don't define HOST_64_BIT here;
+ that's dealt with elsewhere.
+ * hosts/alphaosf.h (sprintf_vma, fprintf_vma): New macros.
+ (uint64_typeHIGH, uint64_typeLOW): Comment with HOST_64_BIT so
+ they get copied to bfd.h.
+
+ * reloc.c (enum bfd_reloc_code_real): Add some Alpha relocation
+ types. Reorganized some of the existing ones.
+ * coff-alpha.c (alpha_howto_table): Construct 64-bit negative one
+ values in case of compilation on a 32-bit machine. Fix pcrel
+ fields of some reloc types.
+ (alpha_bfd_reloc_type_lookup): Handle more relocation types.
+
+ * bfd-in.h (uint64_typeHIGH, uint64_typeLOW): Supply default
+ definitions when not defined, regardless of whether uint64_type is
+ a defined macro or not.
+ (fprintf_vma, sprintf_vma): Define only if fprintf_vma is not
+ already defined.
