Precedence: bulk

PostgreSQL allows to use "COPT" environment variable to add optional
compiler flags at make time.

https://www.postgresql.org/docs/current/install-make.html#CONFIGURE-ENVVARS

Unfortunately pgpool does not have such a mechanism. Attached small
patch adds support for "COPT".

Comments and suggestions are welcome.
