Yes, MXE-octave downloads texinfo 4.13a and cross compiles it for
Windows so that makeinfo is available on the Windows system.  But I
think the problem that Clemens is pointing out is that building the
GCC cross compiler that we use to compile the Windows binary fails
because that step doesn't work with Texinfo 5.x, and 5.x is what he
has installed on his system.  One fix is to also build Texinfo 4.x for
the build system and install it in the local mxe-octave/usr/bin
directory before building the GCC cross compiler.  We already do
similar things for other build tools.  I just didn't realize that
Texinfo would also need special treatment.

If you want to see how we handle the other build tools, take a look at
the src/build-*.mk Makefile fragments.
