On Windows the AVX2 build needs GCC 16: MinGW GCC 15.2 spills 256-bit
values with aligned moves to a stack it cannot align to 32 bytes and the
program faults (aether#2476).
On Windows, before Aether 0.793, the AVX2 build needed GCC 16: MinGW GCC
15.2 spilled 256-bit values with aligned moves to a stack it could not
align to 32 bytes, and the program faulted (aether#2476). Aether 0.793
fixes that; MinGW GCC 15.2 now builds and runs it with the same checksums.
