| dnl fails because of double wrapping because the test further below |
| dnl doesn't work with backslashes. While fixing that test to work |
| dnl might seem better, a lot of the make build backend actually |
| dnl doesn't like backslashes, so normalize windows paths to use |
| dnl forward slashes. |
