Only on i686-w64-mingw64 is DWARF2 used for exception handling; SEH is used on
all the other *-w64-mingw32 targets.

I will debug that. That is easier to build than Ada. Strange that it only
affects 32bit Windows. I will take a look.

Do you by chance an Ada-enabled WIN32 toolchain somewhere that I can use to
build gcc with? Or an script on how to do that? I have not managed to reproduce
the problem yet, unfortunately, because I could not build Ada.

Yes, I can confirm that reverting
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=1c118c9970600117700cc12284587e0238de6bbe
on top of 13.1.0 fixes exception handling, and cmake/ada/gdb work again.
