The obvious defiency with the MSVC build is the lack of inline assembler , MSVC does not support inline assembler , although it has a few compiler intrinsics we can use eg mul and bitscan , but no div/add . I dont know how much difference this makes to Pari , I know with MPIR/GMP it make very little difference as long as you are using assembler for the mpn_* stuff
