We need the -I switch for libpq_srcdir to come before any -I switches injected by configure. Otherwise there is a risk of pulling in a mismatched version of libpq_fe.h from someplace like /usr/local/include, if the platform has another Postgres version installed there. This evidently accounts for today's buildfarm failures on "anaconda". In principle the -I switch for src/port/ is at similar hazard, and has been for a very long time. But the only .h files we keep there are pg_config_paths.h and pthread-win32.h, neither of which get installed on Unix-ish systems, so the odds of picking up a conflicting header seem pretty small. That doubtless accounts for the lack of prior reports. Back-patch to v17 where pg_regress acquired a build dependency on libpq_fe.h. We could go back further to fix the hazard for src/port/ in older branches, but it seems unlikely to be worth troubling over.
