Is that VMS C++ specific pragma or standard?

If VMS C++ specific then maybe it will not be added as I believe John R
want to keep the C++ compiler as close to clang elsewhere as possible.

That seems unlikely to be fixed in the compiler.

Time for int32_t and int64_t?

That sound as a bug.

11.0 is already RC, so maybe go straight to 11 instead of 10.
