/// \brief dump heap allocation stats

/// This works only on microsoft/windows compilers
/// but it's handy to diagnose memory allocation problems.
/// To use, add the following macro in the scope where you
/// want to check memory usage.
///   ACE_WIN32_HEAP_MONITOR(name);
///     where name is a quoted string to label the stats.
/// When the object created by this macro goes out of scope
/// it will write a log message like:
/// (10056|6396) name: New heap blocks: 39; bytes: 19550
///
/// For non-debug, or non-vc builds, the macro expands to nothing
