Errors when compiling an audio driver with ReactOS Build Environment

Question

When I compile the driver's source code (which can be downloaded at https://u.teknik.io/Rq3cw.zip) using ReactOS Build Environment (available at https://downloads.sourceforge.net/reactos/RosBE-2.2.0.exe) and Git for Windows (available at https://git-scm.com/download/win), I get the errors shown in https://paste.ee/p/husrG. I am able to replicate those errors by doing the following:

1. Open a Command Prompt Window.
2. Type cd c:\ and press Enter.
3. Type git clone https://github.com/reactos/reactos.git and press Enter.
4. Close the Command Prompt Window.
5. Install ReactOS Build Environment and set the path of the source to C:\reactos while installing it.
6. Extract the archive containing the driver's source to C:\reactos\drivers\wdm\audio\drivers.
7. Open ReactOS Build Environment.
8. Type configure and press Enter.
9. Type cd output-mingw-i386 and press Enter.
10. Type ninja ac97smpl and press Enter.
