 I'm not _sure_ this is cygwin-related... :-7
But I would be surprised it if there wasn't at least a bit of it.

 My guess is that the above __CYGWIN__ conditional compile is for an older
cygwin version (at least one year old WRT the $Id date).

 Anyone have an idea on how to change it to make it compile?

 Another guess is that cygwin needs

       #include <curses.h>		or ncurses? $ man tputs+ncurses?
       #include <term.h>

 in the right place...

Or is it a  -lncurses  in Makefile.in/Configure.in ?
...  I've spent some time searching/reading in those...
but can't make sense out of it. Configure seems to test for
'tputs' at least  in both 'ncurses' and then 'curses'. This while a '$LIBS'
gets
appended with '-lncurses' (and '-lcurses'), at least temporary.
It seems to me as this '-l<whatever>' never makes it into any Makefile.
(configure and then grep; yields nothing)

The following seems indicate that it HAS found tputs and ncurses...

-- Configure -> defs.h, which contains, among other things  --
/* Define if you have the `ncurses' library (-lncurses). */
/* #undef HAVE_LIBNCURSES */
...
/* Define if you have the <ncurses.h> header file. */
/* #undef HAVE_NCURSES_H */

/* Define if you have the <ncurses/termcap.h> header file. */
/* #undef HAVE_NCURSES_TERMCAP_H */
...
/* Define this if you have the tputs function in an included lib */
/* #undef HAVE_TPUTS */

/* Define this if you have terminfo support */
/* #undef HAVE_TERMINFO */
-- end excerpt --


Another try:
 As BitchX/include/ircterm.h seems to be part of the problem (used in
building term.o)
 I tried this:

$ diff -up ircterm.h ircterm-OLD.h
--- ircterm.h   2003-04-12 20:39:44.000000000 +0200

-#  ifdef __CYGWIN__
-#   include <term.h>
-#  endif
 # endif

 #  include <termcap.h>

...but it doesn't make any difference when it comes to make-ing, the link
and 'implicit declaration' errors/warnings remain.

 Help!? >:-}
