win32 8.1 pgadmin dll issues

My dev box was running 8.1rc1 and I thought it was time to put 8.1 on
it. I downloaded the 8.1 binaries-only dist off of postgresql.org (bt
version), did a binary swap on my server and nothing ran...it turns out
all the binaries like initdb.exe, postgres.exe have a dll dependency on
various pgAdmin dlls like comerr32.dll and several others. pgAdmin was
not installed on my server so nothing worked. I copied the .dlls from
the pgAdmin folder on my workstation and postgres starts up.

Normally I roll my own so this may or may not be an issue...but when did
initdb.exe acquire a pgAdmin dependency?
