I'm getting this error: In file included from ../mesa-24.0.6/src/c11/impl/threads_posix.c:37: In file included from ../mesa-24.0.6/src/c11/threads.h:34: ../mesa-24.0.6/src/c11/time.h:54:8: error: redefinition of 'timespec' 54 | struct timespec | ^ /usr/include/bits/types/struct_timespec.h:11:8: note: previous definition is here 11 | struct timespec | ^ 1 error generated.

I tend to say it's therefore invalid, but CCing Eli as I know the whole unused-commandline-arg thing is a tricky thing for build systems.
indeed, after removal of all --param compilation continues. Thank You!
Yeah, all the "supports compiler flag" checks at minimum are going to invalidly report that clang supports no flags because we have to use that exact "argument unused" error to detect them.
