if you installed zlib correclty you dont need this configure option,
but if you install zlib into your home dir, which is not in the library path of minGW, then you need to tell aMule where to find zlib, thats why the difference
both should work
about the copy paste, should work as it does in putty,
just mark the code/infos to be copied, and then simple go to the place and click strg-v to paste it
