I think this might have to do with flex changing. Does it help if you
"make maintainer-clean"?
My colleague who did the custom build double-checked the flex/bison requirements,
and the version of the packages on the RH7 machine he built on, and they check out (see below).
He also tells me he builds debug and release versions off different workspaces/checkouts,
thus there are no remnants of previous builds, assuming that's what `make maintainer-clean` is for.
Thanks, --DD

On the cf-re7-toolkits (RH7) machine I built postgresql 16.1, the system packages:
$ rpm -qa | grep flex
flex-2.5.37-3.el7.x86_64
$ rpm -qa | grep bison
bison-3.0.4-1.el7.x86_64
are installed in the system. So they look good
