Clang as default compiler November 4th

[Mark Felder]

"Clang produces incorrect code" vs "Clang's floating point has issues" are two different arguments. 

For a mathematical application it would be stupid to use clang if this is the case. I see no problem with it being the default compiler though. If Atlas is in ports the maintainer can just force it to use the latest GCC. 

I'm not sure why Clang being default is somehow a problem for you?
