I'm pretty shocked to learn that configure scripts generated by autoconf 2.50 no longer allow me to use an empty --prefix (i.e. ./configure --prefix= ). This is standard practice when configuring packages for the Hurd, since we pretend we can do without /usr. Of course I can specify --prefix=/, but that's rather ugly, since it results in path names that start with a double /. Would it be possible to allow an empty prefix again in the next autoconf release? Thanks, Mark
