Works fine for me here on 64-bit, and uses standard headers. Maybe you
are using an old version?

The latest version is in linuxconsole SVN:
http://linuxconsole.svn.sourceforge.net/viewvc/linuxconsole/trunk/utils/
Downloadable with SVN command (on one line):
svn co
https://linuxconsole.svn.sourceforge.net/svnroot/linuxconsole/trunk/utils
input-utils

libff is stale project, I suspect this should be filed to linuxconsole
instead (after checking the problems still exist, of course). Hopefully
its maintainers are active. If not, post here.
