issues that caused its inclusion. Is an optimized GCC build any faster for being able to use strict aliasing rules? I dunno. It's still slower than a VC++ build. I did run into two cases where TAutoSegIterator caused intractable problems with breaking strict aliasing rules, so I removed the templating from it, and the caller is now responsible for casting the probe value from void *. - Removed #include "autosegs.h" from several files that did not need it (in particular, dobject.h when not compiling with VC++).
