Warning when compiling on Linux

[nigiord]

I get the following message when compiling from the git repo on Debian 9 (Stretch).

$ gcc --version

Everything seems to work afterwards, but I thought you might want to check that.

I think that warning is safe to ignore as j and k won't be reaching high values.

Yeah, it's nothing to worry about.
