> @mstorsjo I have a fix I will add you to shortly. Thank you for finding this. Do you have the compile command for the whole file? I would like to check that the file now compiles.

I tested, the whole file, and the rest of the project, builds fine now - thanks! (It usually requires you to run configure for the project, to generate a suitable `config.h` for the target, so providing a single command for the full file isn't easy.)
