Sure, this was probably  a weenie that did the initial patch for MSVC.

Possibly it was the first version of the context support.  But instead of
making him do a walk of shame for bringing assembly language into a C++
project, the others did linux and mac ports in binutils.  Nobody thought
about going back for mingw, cross building with mingw from non windows.

Was setjmp longjmp discussed?  Was a walk of shame discussed?

 But maybe there were other issues that forced their hand.
