I take "native" to mean not dependent on a posix-emulation library.

You can use Cygwin or MSYS to build native applications. I've used
MSYS to build gnu make-3.81 and gnu sed-4.0.7 from unmodified FSF
sources, for example. As you say, these native builds probably
perform better than other builds that require an emulation dll,
and not having to modify sources is a very good thing.

Not every package can be built this easily. It's easy for make-3.81
because people who understand how to adapt *nix sources to msw have
worked with the maintainer to make things easy for the rest of us.
Some tools can probably be written completely in portable C (I'd
guess 'rm' would be an example), while others (shells, e.g.) are
much more difficult to get up and running on a different platform.

Would that be a public repository?

Have you considered using
? As I understand it, mingwPORT hosts downloadable patch sets
in a standard template format that makes it easy to grab them
and build them with MSYS. It doesn't incorporate the full source
code, but offers a facility to download it--so it's not identical
to what you want to do, but may be a good means for realizing
your goal. The big advantage for you is that if you share your
patches, others might add enhancements or find and fix problems.

Maybe a concrete example would be clearer: libpng, for instance:
