We've been using this in production for a few weeks (4.6 dev6 and beta1 at least), I just forgot to merge this.

MinGW 13.0.0 with GCC 15.2.1 and binutils 2.45

This will likely require changing this two lines:

-  curl -L -o windows_x86_32.zip $base_url-x86_32-gcc-release.zip
+  curl -L -o windows_x86_64.zip $base_url-x86_64-gcc-13-release.zip
+  curl -L -o windows_x86_32.zip $base_url-x86_32-gcc-13-release.zip

Or if it's working as is, it might be only backward incompatible and lib built with MinGW 12 will work with MinGW 13. Probably better to change it anyway to match runtime version.

Yeah it probably makes sense to change those, I missed that we had two sets of binaries for ANGLE.
