Hello,

I think this is really wrong, because it will use in all cases the
non-optimized generic code, instead of the more optimized assembly code
available for a number of architectures:

$ ls mpn/
alpha  arm  asm-defs.m4  cpp-ccas  generic  ia64  m4-ccas  Makeasm.am  Makefile.am  Makefile.in  mips32  mips64  powerpc32  powerpc64  README  sparc32  sparc64  x86  x86_64  x86_64w  x86w

Best regards,

Thomas
