Missing ERR define

[Wayne Davison <wayned@xxxxxxxxxxxxxxxxxxxxx>]

I'm compiling zsh on a debian sarge system without using the curses
libraries (i.e. I'm not specifying --with-curses-terminfo).  This setup
skips the check for curses.h.  Unfortunately, that means that ERR does
not get defined (since it is only found in curses.h and ncurses.h on my
system), and thus the compiling of Src/Modules/terminfo.c fails.

The attached patch defines ERR to -1 if it is not already defined.  Is
this the right way to deal with this?
