HI,  
I am trying to build the foundationdB 6.3.9 using the docker build env. and I get the following error when running Ninja:

I am running the docker on a rhel7.x env. and the docker version is docker-ce 19.03.5 following the readme.md instruction.  
Could anyone suggest a solution?

Is this a warning or an error? The tip of the release branch runs with -werror I believe, so it would fail there, but I was thinking 6.3.9 permitted warnings.

This particular warning should be resolved later on the 6.3 branch (see [Attempt to fix a build warning that's now blocking the compile due to… · apple/foundationdb@449e4b9 · GitHub](https://github.com/apple/foundationdb/commit/449e4b98b4617773b6bfcd2ff9ca031071e32a89)). If this is failing your compile, you could probably apply the change, switch to a newer revision, or disable -werror in your compile.

It seems like an warning, so will try with the -w flag and see if it goes through
