Yup. I found this after I made the tar file and tried compiling on a
DEC Alpha running DU 4.x, which has the same problem. So now
munge-texi.cc uses the old libg++ Map classes (already, and for a long
time now, distributed with Octave) and should work on systems that
barf on long symbol names.
And some people have dared to wonder why Octave doesn't use the STL! :-/
