    Franz> Hi Richard, the appended small patch fixes it on Linux/PPC.

This patch is correct.  It's something of a design defect, in my
opinion, that the tree-building routines do not automatically set
and a few other such nodes.  I've certainly more than once tracked
down the same bug you found, whereby an expression is not expanded by
expand_expr because it is not marked as having side-effects.

Does anyone disagree?  Otherwise, I'll put together a patch for
`make_node' that fixes this.
