An analysis of C99 DR#236 (type-based alias rules in the presence of
unions) with a possible resolution with a note "Optimizers may have
problems here" has been posted in the posted in the post-Redmond mailing
<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1090.htm>; I'd suggest
people trying to implement aliasing rules read it. Any comments about
what resolutions make sense for optimizing real code would probably best
go to the WG14 reflector (sc22wg14 at open-std.org) though I don't know to
what extent non-member postings are accepted.
