[Proj] Proj 4.9.1RC4 Released

[Charles Karney]

OK, thanks for the explanation.

I only have the most tenuous grasp on the intricacies of exporting
symbols to a dll so I don't think I can have been responsible for this
warning.  It might be worth switching to a shared library as a default
for Windows *after* the release of 4.9.1 to see what breaks.  If
something does break, then there should be some way of fixing it.
