Re: zsh-4.3.4-dev-2.tar.gz

I believe ncurses.h is in the standard place, but not where it is configures looks for and the sources include it:

/usr/local/src/build/zsh-4.3.4-dev-2$ grep 'include.*curses' **/*.c
Src/Modules/curses.c:#include "curses.mdh"
Src/Modules/curses.c:#include "curses.pro"
Src/Modules/curses.c:# include <ncurses.h>
Src/Modules/curses.c:#  include <curses.h>
Src/Modules/curses.c:#include "curses_keys.h"
Src/Modules/termcap.c:#   include <curses.h>
Src/Modules/terminfo.c:# include <curses.h>

/usr/local/src/build/zsh-4.3.4-dev-2$ locate ncurses.h

so, one should have
#include <ncursesw/ncurses.h>

rather than
#include <ncurses.h>

in Src/Modules/curses.c

Perhaps I should add -I/usr/local/include/ncursesw to the CPPFLAGS?

Thanks.  We shouldn't search the ncurses library if we haven't found
the ncurses header.

Obviously it's better to find the header, but the shell may need help doing
that.  I've added a note to the installation instructions.

The last hunk was supposed to add "-expect_unresolved '*'" to DLLDFLAGS on
Tru64 Unix, but the mail I sent seems to have gone astray.  I haven't
tested this.  The idea that the OS still appeared to autoconf as osf* was
suggested by Google but I don't know that for sure either.

 be compiled.  This is likely to be contained on any installation media,
