Yes, but then the final git executable carries around dead code for the
test map and cache types. There are ways to split the macros versus
their instantiation so that the test instantiations only live in the
test-map program, but then that would bring back the "static is not
used" error.
Maybe carrying the dead code isn't that big a deal. It's not that much
extra code.
