Did you run the MPS test suite, and if you did, did all the tests
succeed?

It is not recommended to try the MPS build of Emacs as long as the MPS
library doesn't pass the tests with flying colors.  The patch to
mpstd.h is the first place to look for possible issues.  E.g., why is
MPS_PF_ALIGN 8 and not 16?  Also, did you audit all the places
conditioned on MPS_BUILD_MV and MPS_PF_W3I6MV and made sure they are
conditioned on MPS_BUILD_GC and MPS_PF_W3I6GC when the MinGW64 build
needs the same code as the 64-bit MSVC build?
