C++ Debugging Support library 0.99.47

Libcwd is a full-featured and well-documented library that assists C++ developers with debugging their applications.
C++ Debugging Support library includes support for ostream-based debug output, custom debug channels and devices, memory allocation debugging, run-time sourcefile:linenumber information, and demangled type names of variables. It is thread-safe.
Main features:
- End-users of an application dont need to install libcwd.
- The use of namespaces prevents name collisions between debug channels of different libraries.
- Debug channels and devices can be turned on or off on a per thread basis.
- All debug code can be omitted from the executable by not defining a single CWDEBUG macro.
- Code using libcwd looks clean and is surveyable as a result of using a few well-defined macros, avoiding the need of disturbing #ifdef CWDEBUG ... #endif constructs.
- Debug output is written to an ostream and as such type-safe and customizable as is usual for C++ ostreams.
- An arbitrary number of debug channels and debug devices can be created without any penalty in terms of cpu usage.
- Full support for all forms of iterative and recursive calls.
- Debug output is surveyable as a result of several possibilities to format the output, like a margin string, a marker string, indentation and fixed-width channel labels. All formatting is thread specific.
- Printing the type of arbitrary variables in demangled form.
- Printing addresses in source file:line number presentation.
- Deallocation pointer validation.
- Magic numbers around allocated memory blocks in order to detect buffer overruns.
- Printing an overview of current memory allocations, including start address, size, type of allocated object, source file and line number of allocation and a user definable description.
- Finding allocation information with only a pointer that points inside an allocated memory block, in logarithmic time.
Enhancements:
- This release adds support for x86_64.
