Curl is an awesome tool. Sadly all the dependencies needed, make it so I cannot build an image anymore which is under 4MB, because of a few 200KB. Even throwing out ipv6, opkg and other unneeded things, I could not get it to compile below 4MB.

I will try to solve it myself by replacing the curl calls with something else. I hope that uclient-fetch will support the calls, as this is included in most builds and is suppost to be "a tiny wget replacement"
