NOTE: wchar_t should be defined as a built-in type; no more need to define manually or change project settings. adts: disambiguate iterator type; add operator- as required by VC8 std::equal() implementation precompiled: squelch stupid warning (that informs us that array members are now actually default-initialized as called for by C++) file_cache: remove debug variable This was SVN commit r3464.
