-          # In brief: when "src/lib/small" is in include paths,
-          # `#include <version>` from inside Mac OS SDK headers
-          # attempts to include "src/lib/small/VERSION" as a
-          # header file that leads to a syntax error.
-          #
-          # It was fixed in the following commits:
-          #
-          # * 1.10.10-24-g7bce4abd1
-          # * 2.7.2-44-gbb1d32903
-          # * 2.8.1-56-ga6c29c5af
-          # * 2.9.0-84-gc5ae543f3
-          #
-          # However applying the workaround for all versions looks
-          # harmless.
-          #
-          # Added -f just in case: I guess we'll drop this useless
-          # obsoleted VERSION file from the git repository sooner
-          # or later.
