--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Exactly.  Seems clang doesn't bother with it and allows anything, but it is
unclear if that is the best thing to do.
Is name and comment just a single identifier, or any sequence of any tokens
until end of line?
And, shall the compiler verify proper nestin of these, e.g. reject
#pragma endregion
without earlier #pragma region, or
#pragma region
without termination, or whenever they aren't properly nested?=
