description:
    This package contains the primitive types and operations supplied by GHC.

    It is an internal package, only for the use of GHC developers.
    GHC users should not use it!  If you do use it then expect
    breaking changes at any time without warning.  You should prefer
    to import @GHC.Exts@ from the @base@ package instead.

    -- OS Specific
    if os(windows)
        -- Windows requires some extra libraries for linking because the RTS
        -- is no longer re-exporting them (see #11223)
        -- ucrt: standard C library. The RTS will automatically include this,
        --       but is added for completeness.
        -- mingwex: provides GNU POSIX extensions that aren't provided by ucrt.
        -- mingw32: Unfortunately required because of a resource leak between
        --          mingwex and mingw32. the __math_err symbol is defined in
        --          mingw32 which is required by mingwex.
        -- user32: provides access to apis to modify user components (UI etc)
        --         on Windows. Required because of mingw32.
