I'm not going to include wcwidth in libreadline.  It's not appropriate
for libraries to be conditionally including C library functions -- it
just causes problems down the line.  That's what the calling
application should be doing. 

That said, your fix was better than changing the source, since I don't
see how wcwidth is going to work without wchar.h anyway.
