Libraries on HP-UX 10.20

Libraries on HP-UX 10.20

[Peter Stephenson]

I can't remember if this has been pointed out before, but it's not in
MACHINES: I just compiled zsh 3.1.2 on a local box running HP-UX
10.20.  configure picked -ltermcap for linking, but the resulting zle
behaved very strangely on my xterm.  I replaced it with -lcurses,
relinked and everything is fine.  (At a guess, since changing TERM
gives `terminal unknown' messages, -ltermcap is trying to use the
rather minimal /etc/termcap instead of using the much larger terminfo
database as the emulation in -lcurses does. Hasn't anybody else seen
this?)

This should presumably be written into termcap_curses_order in
configure.in, where it already changes the order for AIX.
Unfortunately I have no idea which other versions of HP-UX will endure
this behaviour.  $host_os in this case is 'hpux10.20'.  This patch to
configure.in applies the change for any hpux10.*.  (Perhaps better to
change the 10 to 1[[0-9]] for future-proofing.)
