Yes, Update 4. Your response suprised me. What I found out after
further tests:

cmake with  -DGMX_SIMD=AVX_256 compiles fine  (only an <algorithm> for 
min/max missing somewhere)

cmake with  -DGMX_SIMD=SSE2 fails on expansion of this said macro
(in bonded.cpp, clincs.cpp)

Hmm, I don't have an AVX machine for testing AMD on windows
at this time. Maybe I can arrange later.
