Can't compile on centos7 about openfpgaloader

[trabucayre]

Seems to be an issue with gcc 4.8. Anyway it's now fixed.
Could you validate and if it's okay close this issue?

Thanks

Compiled with own compiled gcc-8.3.0 and then the program runs fine on CentOS7.
Maybe better to not try support such an old gcc version ?

[Fatsie]

Tried now the different devtoolset versions of software collections and they all seem to generate proper executables. This is g++ v6.3.1 in devtoolset-6, g++ v7.3.1 in devtoolset-7, g++ v8.3.1 in devtoolset-8 and g++ v9.3.1 in devtoolset-9.
It's OK for me to close this issue.

[trabucayre]

Thank for these tests. Really interesting! I must update the README to add this information.
It's true, I'm not sure It's a good idea to try support for this old gcc
Thanks again
