I attached the a tar zip of dummy.t2d, and dummy.texi, and below is the
bash session.

What I see in dummy.t2d/pdf/build/dummy.flz, at lines 84 and 85 is that
dummy.fls is input from the build directoy, not from the bak directory !

Here is the session (with your latest patch):

======================================================================

So from the above, I think that with MikTeX, yes it is working, but this
is not because of your patch, but thanks to some MikTeX trick which I
don't know. This is why I am saying that your patch is not working, I am
meaning that it is not working *PER SE*.

Tell me where I am wrong...


There is another issue, dummy.texi is not run_tex'ed with the
catcode_special for ~, this is because the make_openout_test has caused
catcode_special to go to false.

On the other hand when openout.tex is run_tex'ed, there is some special
catcode for ~, which is useless.

In my first patch there was not this problem: catcode_special was set to
false instead of maybe at the beginning of the script, so that
openout.tex is compiled without this, but then it was set again to maybe
by resolve_use_recorder function. In my second patch, I did it
differently to take into account your remark about the -~ command line
option, so I just do the following in the make_openout_test function:

======================================================================
  save_catcode_special=$catcode_special
  catcode_special=false
  make_tex_cmd
  catcode_special=$save_catcode_special
======================================================================


I think that, if we want to keep your solution, we need to investigate
using -I dummy.t2d/pdf/bak on the command line to see if in this case
MikTeX will make the input from the bak dir, not from the build dir.

Anyway, I still prefer that we should solve it in texinfo.tex, because
that would allow using easily latexmk instead of texi2dvi to do the
job. I like texi2dvi, but I think that it makes texinfo more valuable to
people if we offer some diversity in tools.

VBR,
        Vincent
