1) MSVC does not support VLAs. Use standard fixed C arrays of
maximum size required instead.
2) ../usr/lib/gcc/x86_64-redhat-linux/13/include/emmintrin.h:742:8:
error: array subscript 9 is outside array bounds of 'uint64_t[16]'
{aka 'long unsigned int[16]'} [-Werror=array-bounds=]
3695 742 | *__P = __B;
Compile with -Wno-array-bounds to avoid false positives when
using gcc version 11 or newer (gcc compiler bug/limitation).
