Yes, on win32 with clang/mingw it gets around a weirdness in Microsoft's
Kernel32 implementation, which insists on unwinding the stack.  That
doesn't play well with a number of external libraries, nor with the JIT.
Hence mingw providing a work-around.

It seems that the custom _setjmp in sqSetjmpShim.h gets somehow overridden?

Sorry.  I got confused.  Had too many balls up in the air at the same time
and convinced myself that a #define fix for the above wasn't working.
Hewnce3 I didn't commit a fully functional sqSetjmp.h.  I've got as fix.
Will be committing in a few minutes.  Apologies.

Best regards
