positive:
/EHa
negative:
/EHa-
The positive and negative forms override each other, of course. Additionally, /EHa in its positive form
and /EHa- overrides /D_CPPUNWIND.
The positive form passes to the front-end and back-end compilers for C++ only (C1XX and C2 respectively). The negative form does not pass to any compiler module.
