Description
It looks like the latest commit to the single-header branch broke things. There are a bunch of errors regarding redefinitions (one example is below):
In file included from <source>:11:
/app/raw.githubusercontent.com/kokkos/mdspan/single-header/mdspan.hpp:1111:8: error: redefinition of 'struct std::default_accessor<ElementType>'
1111 | struct default_accessor {
| ^~~~~~~~~~~~~~~~
/app/raw.githubusercontent.com/kokkos/mdspan/single-header/mdspan.hpp:1011:8: note: previous definition of 'struct std::default_accessor<ElementType>'
1011 | struct default_accessor {
| ^~~~~~~~~~~~~~~~
I went back to the previous commit and it worked fine (https://raw.githubusercontent.com/kokkos/mdspan/15563ed9ab955f8a2e555181a71583a9913816c2/mdspan.hpp instead of https://raw.githubusercontent.com/kokkos/mdspan/single-header/mdspan.hpp).

Research direction
Compare the current single-header/mdspan.hpp with the working file from commit 15563ed9ab955f8a2e555181a71583a9913816c2 and reproduce the failure in the reported Godbolt example. Inspect the duplicate std::default_accessor definitions and verify that the single-header version compiles without redefinition errors.
