I haven't. Oracle dont seem to make it easy to do such things (at
least for those of us without support contracts).

Already did (that was my first assumption). Removing them doesn't
help, nor does rewriting them in various strange ways. Removing val++;
(and replacing with { } ) allows compilation to succeed.
I guess the best bet is a compiler update, if I can persuade the
