Update mingw failures to end at GCC-15

[mborland]

Got a report on the mailing list that a user hit this configuration error. Checked our links again, and it looks like the bug has finally been fixed in 10/24

Hi Matt (@mborland)

I think the CI failures are the same ones we just handled in #1306, which has just now been merged to develop

I hopefully just merged the relevant changes in and fired up CI. Let's see if it goes green

Now I see what you mean. That fix took a while. Right on, it's getting better.

@jzmaddock Any chance you can locally test this? There's no runners in CI that have a high enough version of GCC yet.

It looks like pacman for UCRT64 offers GCC 13 at the moment. That's too old right?

I wonder if we could set up a run on Godbolt?

Yes. We have GCC 14 in CI where this was still an issue. Since the bug was patched in 10/24 it should have shipped with GCC 15 in 4/25

Godbolt only has up to GCC 13
