Error running Stan model with rstan 2.21 in Windows

[wds15]

Can u try this:

Not able to run Eight Schools example on rstan 2.21.1 & StanHeaders 2.21.0-5

Can you try setting all of these to CXX14FLAGS=-O3 -mtune=native -mmmx -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2 CXX11FLAGS=-O3 -mtune=native -mmmx -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2 so to avoid the march thing? Apparently there have been issues reported with the minnow compiler and turning on march. Does this resolve the issue?

Please recompile everything Stan related as needed.
