I think this problem is fixed (in a different way) in the current CVS
sources.  If it still does not work correctly for you, please submit
another bug report.

This is not a problem if you use CXX=g++ instead of CXX=gcc.

Would you like to submit a patch to fix this?

| * Makeconf.in:

|  this is a problem when top_srcdir was set to `.' in the root directory

I don't understand why this is a problem.  TEXI2DVI is defined with
`=' so it should be re-evaluated each time it is used in the context
of each sub-Makefile, and each of those should contain a definition
for top_srcdir.  When I configure in the source tree and run make in
the doc/interpreter subdirecotry, I see:

  makeinfo -I. -I./.. octave.texi
  TEXINPUTS=".:./..:.:/home/jwe/tex/macros//::"; \
    export TEXINPUTS; \
    ../../texi2dvi octave.texi

and it works.
