Building from source fails due to treat warnings as errors

[Ty Young]

Hi,

I'm no longer able to build from any source(dev or 10 atleast) on Arch 
Linux due to the following warnings here:

https://pastebin.com/rJqu7Nws

The only two packages that have changed since my last successful source 
build was Gradle and Mercurial(distro package versions). I've tried 
downloading an older version of Gradle(version 4.3.1) but the warnings 
that prevent me from building still show up. Ant version is 1.9.7 but 
I've built using it before and it worked just fine before.

Is there a way I can just ignore these warnings via Wno-error arg?


Thanks.
