Issue Description:

Seems that the typo correction on windows asserts trying to create an anonymous field accessor. This occurred at least in Data.swift in swift-corelibs-foundation trying to typo correct munmap.

I bet this reproduces on other platforms if you can figure out what it was trying to import.

This is due to the use of anonymous fields in structures which Microsoft uses extensively in the Windows SDK. Something like this does the trick:

```
import WinSDK
_ = htont()
```
