zsh 4.3.6 FreeBSD bug

[Phil Pennock <zsh-workers+phil.pennock@xxxxxxxxxxxx>]

Hi,

FreeBSD's conflict in definitions for wchar_t and wint_t if ncurses.h is
included with _XOPEN_SOURCE_EXTENDED defined (conflict with stddef.h and
wchar.h) means that zsh 4.3.6 fails to build on FreeBSD 6.2/amd64.

There's already logic in configure/configure.ac to handle OpenBSD
specially.  If I just add *freebsd* to the OS check, zsh builds fine for
me.  I don't know enough to know why this wasn't needed for you, unless
it only affects 64-bit.

I just hacked configure directly to avoid an autoconf rebuild.

This _should_ do it for a rebuild case (untested).
