/*
* 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().
