Note that I didn't say 64-bit. Baby steps, first the tried-and-true 32-bit compiler.

Funny I came with almost exactly the same patch.

I did:
% make CC=i486-mingw32-gcc NO_OPENSSL=1 NO_GETTEXT=1
But ideally it should be:
% make CROSS_COMPILE=i486-mingw32-
(or whatever the name of the suite)

I see those errors with a 64-bit compiler, but not with the old 32-bit one.

I get the same error. I've been cross-compiling since basically all my professional life, so I don't think you are doing something wrong, it just doesn't work.
