move all except user-specified config choices out of config.h and into appropriate headers CPU_IA32 -> ARCH_IA32 wsdl: disable use of ddraw (will soon be replaced by WMI) use shared_ptr without namespace qualifier (it's in tr1) debug_warn -> debug_assert(0) LIB_API to allow building as DLL smart pointers: reduce use of .get() cache_adt: use map instead of hash_map (avoids needing a hashCompare class). also remove spurious warning code_annotation.h: better cassert implementation move FPS measuring portion of timer.cpp into frequency_filter move include of memory headers into mmgr.h (to avoid errors, we must ensure they are included if mmgr is used) posix_filesystem.h: move definition of mkdir to wfilesystem stl: disable iterator checks in release mode wmi: fix COM init bug, use smart pointers wutil: add code to get DLL module handle (if compiled as such), add WinScopedLock timer: fix handling of raw ticks This was SVN commit r5517.
