Indeed, but there seems to be another problem now: "make install" does
not always replace the shared libraries in the destination directory.
This breaks the Debian build, which relies on installing the non-wide
libraries first, then the wide ones.  In my test build, dpkg-gensymbols
complained about missing symbols in libtinfo.so.6 because of that.

Thanks for working on this issue.
