Whoever wrote that doesn't seem to have bothered to read the GPL. The
language of the GPL is exceedingly clear and specific:
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
It says THIS LICENSE. There is nothing at all about "compatible
licenses" anywhere in the document. (Quote taken directly from the copy
of the GPL in readline-4.2a.tar.gz.)

... and they are all GPL-licensed.
The fundamental problem here is that we don't want the Windows
distribution of PG to become effectively GPL-licensed. There's no
issue if someone builds their own copy and doesn't redistribute it,
but there is a big issue if we are distributing a heavily used port
in a way that violates someone else's license.
