  No, since "if Sometimes then" can't appear in a declaration part.
You might be able to
if Sometimes then
  declare
     ..... do all the 32 bit declarations and usage thereof
  end;
else
  declare
     ... do the 64 bit version
   end;
end if;
if that doesn't generate other problems.  Tucker Taft's solution of
putting the variable stuff into different variants of a low level
package is what I've done in the past, though.
