--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
The -Wformat checkers can't detect using the HOST_WIDE_INT_PRINT because by=
 the
time they run macros have been expanded and adjacent string literals
concatenated.  They can only detect this problem when compiling for the tar=
gets
with the unsupported format directives (like %I64d), which I would expect t=
hey
already do.

The problem could be detected by some script, maybe the one that scrapes the
format strings out of the sources and generates the gcc.pot file.  IMO, a g=
ood
time to do this is either during bootstrap, or during make check, regardles=
s of
the target.

Anyway, the problematic code is still there in GCC 12(see below) so confirm=
ed.

          if (type !=3D CPP_EOF)
            error ("junk at end of %<#pragma CTABLE_ENTRY%>");
          else if (i >=3D ARRAY_SIZE (pru_ctable))
            error ("%<CTABLE_ENTRY%> index %" HOST_WIDE_INT_PRINT "d"
                   " is not valid", i);
          else if (pru_ctable[i].valid && pru_ctable[i].base !=3D base)
            error ("redefinition of %<CTABLE_ENTRY "
                   "%" HOST_WIDE_INT_PRINT "d%>", i);
          else
            {
              if (base & 0xff)
                warning (0, "%<CTABLE_ENTRY%> base address is not "
                            "a multiple of 256");
              pru_ctable[i].base =3D base;
              pru_ctable[i].valid =3D true;
            }=
