That's theoretically interesting, but I don't think it's a gawk issue. If I'm
not mistaken, gawk multiplies numbers either by using the CPU's built-in
multiplication capability for integer or floating-point values, or by using a
compiler algorithm if the CPU doesn't directly support multiplying the types in
question, or by using the mpfr library when -M is used.  So if this new
algorithm is to be used, it will have to be implemented in the CPU, the C
compiler, or the MPFR library. I think the only place this might be
relevant is in the MPFR library for handling very large numbers...
