One of the failing test cases is for seg_over_left, which is so trivial
that it's pretty hard to believe even a Microsoft compiler could get it
wrong ;-).  My bet is something wrong in segparse.y or possibly
segscan.l, leading to garbage seg values being produced.  We've seen
segparse.y trigger compiler bugs before --- look at its CVS history.
