Comment (by carsten):

 Well, I'm no expert in portability, but I think it should be portable.
 - there is a check that the length of bytestring equals the length of the
 internal representation of double in "if ( s->Len() != sizeof(d))".
 - the bit-pattern is first translated from network to host order before it
 is interpreted as double, to avoid invalid bitpatterns as may occur in
 - the bitpattern interpretation for a double is defined in IEEE 754,
 http://en.wikipedia.org/wiki/Double-precision_floating-point_format and I
 just *expect* every compiler on every platform to adhere to this spec.
