Feel free to forward this to him:

As long as you can provide the exact source code required to regenerate the
DLL that you are providing and you advertise the fact that you will make
it available on request, that should be fine.  Pointing elsewhere is not
acceptable unless you have made an arrangement with another site to provide
the sources for your binaries.  We do not offer this service since we only
keep the source code for the last couple of releases around.

We see these types of issues all of the time.  We've asked Richard
Stallman about this issue and he pointed us to the FSF GPL FAQ,
specifically:
