‘mvwin_wchnstr’ was not declared in this scope when building with --without-ncursesw

lnav version 0.9.0

Describe the bug A Gentoo maintainer has reported that lnav fails to compile. I noticed that they had been building with --without-ncursesw, which seems to be a reproducer for me as well. This is the snippet of the error message that I see when I reproduce it:

To Reproduce Steps to reproduce the behavior:

• git checkout 0.9.0
• ./autogen.sh
• ./configure --without-ncursesw
• make -j8 (I don't think the -j8 is important, but that's the way I built it.)
