When changing a few files on Windows (MinGW) and re-running make, the 
following rule causes an error:

"$?" gives only the recently changed files but MinGW needs all files 
("$^") to build the DLL. This will cause a lot of "undefined reference 
to..." errors.

I currently don't have my GNU/Linux machine at hand so I cannot test 
whether "$^" would cause any problems there. (Though I doubt it).

(I think this problem was already described by others, but I didn't find 
the threads now.)
