* 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:

*
* 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.
* The comprehensive exception list is included in ntstatus.h from the
* Windows Driver Kit (WDK). A subset of the list is also included in
* winnt.h from the Windows SDK. Defining WIN32_NO_STATUS before including
* windows.h helps to avoid any conflicts.

* Some day we might want to print descriptions for the most common
* exceptions, rather than printing an include file name. We could use
