+ *	Signal stuff
+ *
+ *	For WIN32, there is no wait() call so there are no wait() macros
+ *	to interpret the return value of system().	Instead, system()
+ *	return values < 0x100 are used for exit() termination, and higher
+ *	values are used to indicated non-exit() termination, which is
+ *	similar to a unix-style signal exit (think SIGSEGV ==
+ *	STATUS_ACCESS_VIOLATION).  Return values are broken up into groups:
+ *
+ *	http://msdn2.microsoft.com/en-gb/library/aa489609.aspx
+ *
+ *		NT_SUCCESS			0 - 0x3FFFFFFF
+ *		NT_INFORMATION		0x40000000 - 0x7FFFFFFF
+ *		NT_WARNING			0x80000000 - 0xBFFFFFFF
+ *		NT_ERROR			0xC0000000 - 0xFFFFFFFF
+ *
+ *	Effectively, we don't care on the severity of the return value from
+ *	system(), we just need to know if it was because of exit() or generated
+ *	by the system, and it seems values >= 0x100 are system-generated.
+ *	See this URL for a list of WIN32 STATUS_* values:
+ *
+ *		Wine (URL used in our error messages) -
+ *			http://source.winehq.org/source/include/ntstatus.h
+ *		Descriptions - http://www.comp.nus.edu.sg/~wuyongzh/my_doc/ntstatus.txt
+ *		MS SDK - http://www.nologs.com/ntstatus.html
+ *
+ *	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 an include file name.	We could use
+ *	RtlNtStatusToDosError() and pass to FormatMessage(), which can print
+ *	the text of error values, but MinGW does not support
+ *	RtlNtStatusToDosError().
