It seems that the strange failure (core dump) of

t/uni/fold.t on ithreads Solaris builds is a gcc bug:
(1) using Sun's cc helps
(2) rewriting the ithreads PM_SETRE() to do the
    setting in two steps helps
(3) no other platforms have the crash
(4) Tru64's Third Degree sees nothing evil
So we implement (2).
