I don't know very much about all these details, but if what we are 
trying to do is invoke a callback whenever an exception is thrown (even 
if a custom assembly wrapper callback statically linked in the 
executable which calls the the mingwm10.dll functions, also statically 
linked in the executable) then this shouldn't be so difficult, right?

Are there places where the MS-C-runtime-dlls invoke function pointers 
during exception handling?
 Well, ok, *those* might be subject to change (but maybe it depends)...
