A quick follow up to this one.  The bug does NOT occur if I substitute
eqnarray for eqnarray*.  I believe that this means that the constant
org-latex-entities in org-latex.el needs to be modified to admit the
starred (unnumbered) variants of the latex math operators.

Unfortunately, my simple-minded attempt to butcher in stars has run
aground on the shoals of my ignorance of the combination of emacs-lisp
string escapes, and emacs regexpressions.  Simply adding


to that list won't work, and even


doesn't seem to do the right thing.  if anyone can put me on the right
track, I'll try to provide a patch.
