(_bfd_XXi_swap_scnhdr_out): Compute ps and ss differently for object files and
executables. (coff_swap_scnhdr_in): Only set the s_size field for object files or for executables who have not already initialised the field. (bfd_pe_executable_p): New macro. Return true if the PE format bfd is an executable.
