In krlmlr/r-appveyor#167, @krlmlr advises to set PKGTYPE: source

I'm trying that right now, and though it took forever, both the x64 and i386 devel versions built successfully. I'll try committing a trivial change on my fork to see if these packages have been cached and maybe it will run faster this time...

[bokov]

Darn. It re-compiles everything. I guess until CRAN creates the 4.0 subdirectory on their repos, it's a choice between: not committing anything, committing but not testing devel versions on Windows, or having very slow devel builds.

If you want to go with slow builds, I have a PR ready to submit.

This is the PR in question:
https://ci.appveyor.com/project/bokov/rio/builds/28093351

It took 1 hour 25 minutes to run, but it's green.

It is no longer necessary to use PKGTYPE: source in appveyor.yml for now. But this problem may repeat with the next version bump ( krlmlr/r-appveyor#167 )
