  /*
   *	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
!  *
!  *	Some day we might want to print descriptions for the most common
!  *	exceptions, rather than printing a URL.
