The VS2017 patch applies cleanly to 9.5, so that seems easy. The VS2015 
patch from 9.5 needs a very small amount of adjustment by the look of it 
for 9.3 and 9.4, after which I hope the VS2017 patch would again apply 
cleanly.

I'll try to put this together.

The trouble with not back patching support to all live branches as new 
versions come in is that it acts as a significant discouragement to 
buildfarm owners to use the latest Visual Studio versions. I've never 
argued stringly on this point before, but I think i'm goiung to ber 
inclined to in future.

Meanwhile, I will turn bowerbird back on but just for >= 9.6 for now.

cheers
