Thanks, I seem to have removed the list by accident ...

Yes.

Well, I would like to have both, I just started with 64-bit.

I tried it again with TARGET=i686-w64-mingw32.static, which led to the
same warnings/errors.

You say this should work?

I also tried TARGET=i686-pc-mingw32.static, but this immediately gave me:

Makefile:334: *** Deprecated target specified:
"i686-pc-mingw32.static". Please use i686-w64-mingw32.[static|shared]
instead.  Stop.

No problem, thanks for you help anyway!
