Hi, I wanted to let you know that I have today looked into the very same FTBFS and submitted the fixes upstream.
https://lists.quagga.net/pipermail/quagga-dev/2020-October/033390.html https://lists.quagga.net/pipermail/quagga-dev/2020-October/033391.html With those two gcc-10 builds work. [1] contains an (Ubuntu) Test build with these applied. You might wait for upstream to integrate or apply them as-is to fix the FTFBS.
