GCC 6.1 compilation fails on CentOS 7.2 - conflicting/ambiguous definitions

Hello,

I’m trying to compile GCC 6.1 on CentOS Linux release 7.2.1511. The configure stage works fine, but when I run “make” it fails with the following errors. Any pointers would be greatly appreciated. I’ve also attached the contents of config.log in case that helps.

Thanks so much,
Daniel
