LLVM C API has an incorrect prototype in <llvm-c/Transforms/PassBuilder.h>
that compilers complain about with -Wstrict-prototypes.
/usr/local/include/llvm-c/Transforms/PassBuilder.h:53:55: error: this function
declaration is not a prototype [-Werror,-Wstrict-prototypes]
LLVMPassBuilderOptionsRef LLVMCreatePassBuilderOptions();
^
void
1 error generated.
This has been fixed in upstream
llvm-project commit 2f53fcc831e2f5ceee0d42c41766d9231049e46b.
The header fix could be applied to OpenBSD base system as well.
However, the error does not show up there because clang appears
to apply some implicit/legacy C rules to headers under /usr/include.
