PR24392, Clang warning Wtautological-constant-out-of-range-compare
PR 24392 * configure.ac: Invoke AC_CHECK_SIZEOF(int). * configure: Regenerate. * coffgen.c (coff_get_reloc_upper_bound): Replace gcc diagnostic workaround with SIZEOF_LONG vs. SIZEOF_INT check. * elf.c (_bfd_elf_get_reloc_upper_bound): Likewise. * elf64-sparc.c (elf64_sparc_get_reloc_upper_bound): Likewise. * mach-o.c (bfd_mach_o_get_reloc_upper_bound): Likewise.
