* It seems the exception lists are in both ntstatus.h and winnt.h, but
* ntstatus.h has a more comprehensive list, and it only contains
* exception values, rather than winnt, which contains lots of other
* things:
*
* http://www.microsoft.com/msj/0197/exception/exception.aspx
*
* The ExceptionCode parameter is the number that the operating system
* assigned to the exception. You can see a list of various exception codes
* in WINNT.H by searching for #defines that start with "STATUS_". For
* example, the code for the all-too-familiar STATUS_ACCESS_VIOLATION is
* 0xC0000005. A more complete set of exception codes can be found in
* NTSTATUS.H from the Windows NT DDK.
*
* Some day we might want to print descriptions for the most common
* exceptions, rather than printing a URL. FormatMessage() can print
* the text of error values, but not exception values.
