The patch made sure the ncursesw library was not selected to save space,
but that library doesn't exist in this distribution at all.

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.

I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.

However, I can not garantee that I always picked the correct information
and/or did not miss license information.

Most significantly, includes IPv6 support.  This version forces
libncurses, by patching the configure script, instead of allowing
libncursesw, saving (~65k) image space.
