Browse source 
This workaround should no longer be relevant since we don't support
building against libunwind headers from LLVM 14.

// TODO: This is a temporary workaround for libc++abi to recognize that it's being
// built against LLVM's libunwind. LLVM's libunwind started reporting _LIBUNWIND_VERSION
// in LLVM 15 -- we can remove this workaround after shipping LLVM 17. Once we remove
// this workaround, it won't be possible to build libc++abi against libunwind headers
// from LLVM 14 and before anymore.
