Since it's just a cleanup I don't see any need for it to be in edk2-stable202303.

Do you think this needs to be considered for edk2-stable202302?

Thanks,

Subject: [edk2-devel] [PATCH 1/2] MdePkg: Update Base.h to be compliant with C11

With the introduction of the use of _Static_assert, edk2 requires a C11
compatible compiler. Update Include/Base.h to be compliant with C11.

As of C11, the maximum type of an enum is type `int`. Since the UEFI
Specification 2.3.1 Errata C allows either `int` or `unsigned int`, fix
the 32-bit enum check to use a signed int.

Since the UEFI 2.3 Specification only allowed signed int, update the
comment to reference 2.3.1 Errata C where the change was made to allow
unsigned int.
