That's the first thing I attempted, but the MSVC compiler is uncooperative.

If you try to redefine memset/memcpy, you get the following compiler error:

error C2169: '_memcpy' : Intrinsic function, cannot be defined

And of course, this means that you then have to link with the standard 
Windows MSVC libraries, which creates issues when building UEFI drivers...

Apparently, there used to be a way to disable intrinsic functions with 
older versions of Visual Studio (using a pragma), but this capability 
was removed in the latest versions. Either that, or Microsoft does not 
consider memcpy and friends as belonging to the general "intrinsic" 
category that the compiler can disable.

This means that, right now, the only option available is to patch the 
GRUB source.
