SB-Prolog grew up in a Sun-{2,3}/Vax environment, and assumes that it's
enough for longwords (in the WAM byte code) to be word-aligned (i.e. have
even addresses).  Some machines require that longwords be longword-aligned,
i.e. have addresses divisible by 4: SBProlog won't port very easily to these.
My understanding is that the Pyramid-90x and the Sun-4 are such machines.
Sorry.
