What does "makeinfo --version" say? I use version 4.8. Also, does it work to invoke "makeinfo --force emacs.texi" from the command line in the C:/trunk/doc/emacs directory, or does it crash in the same way?
You know what? It says makeinfo: missing file argument. Try `makeinfo --help' for more information. which produces the same thing. I think that I don't have a working Texinfo, will investigate. Thanks.
