All I meant was that there is nothing inherently 64 bit about spice. The
marshalling code does make for an easy place to deal with endianess of the
protocol vs the machine. A quick grep shows there is SPICE_BYTESWAP in macros.h
and it is used by generated_demarshaller.c (and I'll assume the others). 64/32
is something that needs other checking. I'd assume if someone got to building it
on 32 bit they will find pretty fast if there is anything to fix.
