On Windows, winapi no longer builds with latest pc-windows-gnu nightlies

[Osspial]

This error seems to have been introduced by rust version 1.40.0-nightly (6767d9b90 2019-10-11). To reproduce, clone https://github.com/retep998/winapi-rs.git on a Windows system and build with nightly-2019-10-11-x86_64-pc-windows-gnu. Building with nightly-2019-10-10-x86_64-pc-windows-gnu seems to work fine, though.

This was discovered with Winit's Appveyor builds started failing on the latest nightlies. This is the latest working build log, and this is the first failing build log

For reference, here is the relevant error:
