[Pkg-octave-devel] Bug#790626: Octave FTBFS With Texinfo 6

[Norbert Preining]

Hi Scott,

ok, here is what you have to do, but I cannot *fully* fix it 
as the problem comes from 
	munge-texi.pl

What needs to be done are three things:

* add texlive-fonts-recommended to the build deps
  this is necessary for newer texinfo (although nobody knows why ;-)

* do NOT use the shipped texinfo.tex, and at the same time also don't
  use the shipped texmf.cnf
  the shipped texinfo.tex is too old and needs to be dropped
  the texmf.cnf change is not necessary anymore

* finally the critical part - fix the argument processing in texinfo source
  the problem is basically that 
	munge-texi.pl
  creates code like
	@qcode{"\a"}
  which needs to be changed to
	@qcode{"\\a"}

  THere are *two* occurrences, one in expr.texi (@nospell{"\0"}) and one
  in errors.texi (@qcode{"\a"}). Below patch changes that in the 
  *generated* texi files, but when doing a full rebuild these changes
  are overwritten, so one needs to look into the munge script.

I confirmed that with the above changes, the documentation builds
without any problem.

What is left is to find the fix for the txi -> texi munging.

Hope that helps
