https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64384 is another GCC bug report about the same issue.

For the ISO volatile loads/stores, if I understand correctly, e.g. `__iso_volatile_load32(__int32 const volatile *ptr)` could be implemented e.g. like this for mingw targets: ``` __int32 SOME_INLINE_ATTRIBUTE __iso_volatile_load32(__int32 const volatile *ptr)...

No, those aren't files with names ending with `.Msi`, they are listed with `"type": "Msi"` in the download manifest. Currently, `.msi` files are only unpacked as part of the Win10SDK...
