curl/lib/setup.h
Daniel Stenberg c688166066 check for and require tld.h to be present before libidn usage is activated 
in the build, since libidn 0.3.X didn't have the header and we don't support
that old libidn versions anyway.

This was mentioned on the list by Jean-Philippe Barrette-LaPierre and in bug
report #1062264.
