The 64 bit backend may only be used if the host compiler supports 64
-ints (eg long long with gcc), by defining the name @code{HOST_64_BIT} in @code{bfd.h}.
+ints (eg long long with gcc), by defining the name @code{BFD_HOST_64_BIT} in @code{bfd.h}.
With this name defined, @emph{all} bfd operations are performed with 64bit
arithmetic, not just those to a 64bit target.
