--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That is because most targets define POINTER_SIZE as (condition ? 64 : 32) or
constant while rs6000 as a variable holding it, therefore whether it chooses
unsigned or signed type for it then matters in these cases.

I tried that and it now compiles ok.

dwarf2asm: Fix bootstrap on powerpc*-*-* [PR98839]
My recent dwarf2asm.c patch broke powerpc*-*-* bootstrap, while most target
define POINTER_SIZE to (cond ? cst1 : cst2) or constant, rs6000 defines
it to a variable, and the arbitrarily chosen type of that variable
determines
whether we get warnings on comparison of that against signed or unsigned
ints.
Fixed by adding a cast.
