I tried this on the master Cygwin and get the same error.

```
$ head config.log | grep newlib-cygwin
  $
/usr/local/src/cygsimple/sf/build/newlib-cygwin/src/newlib-cygwin-2.11.1/configure
--prefix=/usr --host=x86_64-pc-cygwin --build=x86_64-pc-cygwin
--target=x86_64-pc-cygwin --sysconfdir=/etc --sharedstatedir=/var
--localstatedir=/var
```

What configuration item should I add to avoid this?
