[Lynx-dev] CF_FIND_LINKAGE

[Thomas Dickey]

I can use most of DK's changes (thanks...), but this one raises an issue.
If I'm reading it right, it's allowing the search for includes and libraries
to look in uncorrelated directories.  If so, that would break things like
the check for ncurses, which may have a curses.h conflicting with other
implementations.  So I'm asking for more information - what specific problem
is it fixing?  (can we fix it in a different way).
