- Went back to using RDTSC for timing on Win32. Ironically, QueryPerformanceCounter() is obviously using the TSC for its timing on my machine, yet the overhead it has to do to keep the timer sane is apparently noticeable on a few maps. I suppose I should at some time check clock_gettime() and see if it has similar issues on Linux. SVN r1460 (trunk)

- Removed -fno-strict-aliasing from the GCC flags for ZDoom and fixed the 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++).
