  -- Prior to GHC 9.4, Windows GHC bindists bundled a GCC-based C toolchain,
  -- which requires linking against the GCC library to handle some of the
  -- compiler intrinsics that appear in the optimized code. Moreover,
  -- dynamically linking against the GCC library proves fragile, so we force
  -- static linking by providing the full name of the static GCC library
  -- archive.
  --
  -- On GHC 9.4+, Windows GHC bindists ship a Clang-based C toolchain. Clang
  -- optimizations don't appear to require linking against anything in
  -- particular, so it just works out of the box.
