I can confirm that this fixes the compilation with --without-wc-funcs on FreeBSD.

I think wcwidth is available on all major platforms. Even if not, having a workaround only for this function would already greatly simplify the code. And to find out if anybody still needs the workarounds, the easiest method is to deprecate them and see if anybody complains. So I support that.
