- * Revision 1000.2 2004/02/12 21:43:57 gouriano
- * PRODUCTION: UPGRADED [CORE_001] Dev-tree R1.9
- *
- * Revision 1.9 2003/12/09 21:13:27 ucko
- * Re-tweak logging of 64-bit numbers, as the previous revision broke
- * when __int64 and long long were synonymous. (Now uses Int8/Uint8
- * everywhere, but only when sizeof(long) < 8.)
- *
- * Revision 1.8 2003/12/09 17:25:51 gouriano
- * Corrected previously defined Log() functions to avoid conflicts
- * on 64 bit platforms
- *
- * Revision 1.7 2003/12/09 16:55:12 gouriano
- * Added Log() methods for Int8 and Uint8
- *
- * Revision 1.6 2003/11/12 20:15:23 gouriano
- * Added more Log() methods: for short, int, and char* types
- *
- * Revision 1.5 2003/05/19 21:05:39 vakatov
- * x_InsertPageBreak() -- title: "" -> kEmptyStr, len: int -> unsigned int.
- * Fixed code indentation and simplified some code.
- *
- * Revision 1.4 2002/12/18 22:53:21 dicuccio
- * Added export specifier for building DLLs in windows. Added global list of
- * all such specifiers in mswin_exports.hpp, included through ncbistl.hpp
- *
- * Revision 1.3 2002/05/29 21:15:08 gouriano
- * changed formatter interface: added value type
- *
- * Revision 1.2 2002/05/28 17:57:11 gouriano
- * all DebugDump-related classes were put in one header
- * templates adjusted and debugged on multiple platforms
- *
- * Revision 1.1 2002/05/17 14:25:39 gouriano
- * added DebugDump base class and function to CObject
- *
