It applies to both code lines, as I wrote. It's already in the CVS.

It's also possible that the C compiler (this is not gcc by the way)
generates far less than optimal code. The heavy duty programs were
generally written in Fortran if I'm not mistaken. In general I would
suspect that GNU Go doesn't take advantage of a single one of the good
features of a Cray Y-MP. Still it's striking how extremely bad it
