CFLAGS=-Werror breaks a whole lot of configure's tests, not only that one. (We even have this documented, see [1].) So you can't inject -Werror that way. What I do on my buildfarm animals is the equivalent of export COPT='-Werror' after configure and before build. I think configure pays no attention to COPT, so it'd likely be safe to keep that set all the time, but in the buildfarm client it's just as easy to be conservative. regards, tom lane [1] https://www.postgresql.org/docs/devel/install-make.html#CONFIGURE-ENVVARS
