C:\Users\siffiejoe\Sources\temp\lua52>install
Der Befehl "install" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.

C:\Users\siffiejoe\Sources\temp\lua52>
```

So to sum this up:
*   `make` in MinGW is broken, you have to use `mingw32-make`.
*   Windows `mkdir` cannot handle `-p` and/or multiple arguments
*   there is no `install` command on Windows
*   I *do* however have an `rm` in my PATH. I don't know where it comes 
from, but it's not in the MinGW directories ...

And btw.:

That's why you probably shouldn't use GNU make features in a portable 
Makefile ...
