I'm happy to do so.  Can you point me to where in the Fuchsia sources fenv.h lives? Is it:
- https://fuchsia.googlesource.com/fuchsia/+/refs/heads/main/zircon/third_party/ulib/musl/include/fenv.h
- https://fuchsia.googlesource.com/fuchsia/+/refs/heads/main/zircon/third_party/ulib/musl/include/bits/fenv.h
- https://fuchsia.googlesource.com/fuchsia/+/refs/heads/main/zircon/third_party/ulib/musl/include/bits/aarch64/fenv.h
- https://fuchsia.googlesource.com/fuchsia/+/refs/heads/main/zircon/third_party/ulib/musl/include/bits/riscv64/fenv.h
