bind-9.18.31 compile errors RHEL 7.9

[N M]

What changed between bind-9.18.30 and bind-9.18.31 that would cause it to not 
compile? We can compile bind-9.18.30 just fine but bind-9.18.31 fails with 
netmgr/udp errors:

Mark,

Thanks for the suggestion. That did the trick. We will be upgrading our RHEL 7 
systems this year but the RHEL 8 systems will take more time. This gives us a 
solution until we can get all of our DNS servers to RHEL 9.
