This shouldn't be a mere "Note:" but should be treated as an
integral part of the implementation details.

    Move the global variable 'has_symlinks' into the
    'repo_config_values struct.

    Introduce 'repo_has_symlinks()' getter for readability,
    and 'platform_has_symlinks()' macro to allow platform
    specific customization, primarily to help MinGW.

may be sufficient.

The changes to compat/ looked reasonable to me.

Thanks.
