It's a directive for the linker to use libncursesw instead of libncurses.  On a
Fedora 13 machine I see these INPUT directives as well, e.g.:

/usr/lib64/libbfd.so:INPUT ( /usr/lib64/libbfd.a -liberty -lz )
/usr/lib64/libcurses.so:INPUT(-lncurses)
/usr/lib64/libcursesw.so:INPUT(-lncursesw)
/usr/lib64/libncurses.so:INPUT(libncurses.so.5 -ltinfo)
/usr/lib64/libncursesw.so:INPUT(libncursesw.so.5 -ltinfo)
/usr/lib64/libopcodes.so:INPUT ( /usr/lib64/libopcodes.a -lbfd )

etc.

However, Fedora and Ubuntu don't seem to unify libncurses and libncursesw.
