/usr on MSYS2 is mounted to /
and there are no difference between /bin and /usr/bin. I'm modify makepkg
and makepkg.conf to support mingw targets. Also I prefer to split packages
to binaries, development files, documentation and so on rather then just
pack all in one archive.
Also MSYS2 in default config doesn't support creating symlinks. You can
enable native windows symlinks but they need special privileges and you
need to start msys from admin account.
