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.

 On some systems a suitable development package with a name such as
 curses-devel or ncurses-devel needs to be installed before zsh can
 be compiled.  This is likely to be contained on any installation media,
