-          # The following lines add two tweaks:
-          #
-          #  1. Change the linker name to "x86_64-w64-mingw32.static.posix-gcc.exe".
-          #  2. Add empty libgcc_s.a and libgcc_eh.a, and add them to the compiler's
-          #     library search paths via `LIBRARY_PATH` envvar.
-          #
-          # The first tweak is needed because Rtools42 doesn't contain
-          # "x86_64-w64-mingw32-gcc," which `rustc` uses as the default linker
-          # for the `x86_64-pc-windows-gnu` target.
-          #
-          # If we use the Rtools' toolchain, the second tweak is also required.
-          # `rustc` adds `-lgcc_eh` and `-lgcc_s` flags to the compiler, but
-          # Rtools' GCC doesn't have `libgcc_eh` or `libgcc_s` due to the
-          # compilation settings. So, in order to please the compiler, we need
-          # to add empty `libgcc_eh` or `libgcc_s` to the library search paths.
-          #
-          # For more details, please refer to https://github.com/r-windows/rtools-packages/blob/2407b23f1e0925bbb20a4162c963600105236318/mingw-w64-gcc/PKGBUILD#L313-L316
