Bug#848220: g++-4.9/g++-5 show floating point diff to g++-6/g++-7

[Steffen Möller]

Hello,

I just introduced g++-5 as a build dependency to 
https://packages.qa.debian.org/b/boinc-app-eah-brp.html because of small 
- but very present - runtime differences. It had helped me a lot to have 
g++-5 in unstable so I could just go and test. You certainly have 
reasons to remove it, but please be aware of this downside. I can well 
imagine that for many industrial settings the parallel availability of 
both versions is helping the transition.

Cheers,

Steffen
