Appveyor MinGW - bundled gems missing?
I just noticed that the Appveyor MinGW build is not showing the installed bundled gems in the console output, although the mswin build is.
Since this part of the install recently broke, I checked an earlier rev (r64550), and it shows the same thing, (mwsin ok, mingw missing.)
It's been a long time since I needed to revise the bundled gem code in ruby-loco, and it's set up to cache the gems on Appveyor & also if one is building locally.
I don't know if this is considered an issue, but someone trying to build locally using the scripts might be surprised.
