Hi Matthew,
you are completely right, we are re-inventing wheels here.
I have just pushed a fix which will use texi2dvi when available.
The echo area will now also give an indication of the kinds
of errors that happened during the final pdflatex run.
This is a big improvement, thanks to Sebastian for kicking
off this discussion, and to all who contributed.
Please test the new processing and let me know if there
are problems.

Hi,
I don't know if you are aware, but there is a utility called
texi2dvi that figures out how many times LaTeX, bibtex, etc. need to
be run and automatically runs them the correct number of times for
you. It also has an option -p that uses pdflatex and generates pdf
instead of dvi. In my opinion, it would be better to make use of
this rather than writing new code to do this, as they have thought
about all the edge cases in far more detail than is possible here.
It is possible that some LaTeX installations do not come with
texi2dvi, but it does come with the full TeXLive installation so
plenty of people are likely to have it installed. If you want to
avoid this breaking on systems that do not have texi2dvi installed
then you could just check for it, use it if it is available and, if
not, give the user a warning message that they may get better
results if they install texi2dvi whilst using the existing code.
Best,

Could you make your latest sentence more explicit?

I guess things in that direction are entirely possible. I don't use
bibtex
yet, but will have a look at a better integration.

Good question! Yes, I implicitly wrote in bash. That won't work for
sure in
Windows...
But, then, how do we do for writing such shells in Emacs? Go to
Emacs's
builtin shell? I have no experience with it, but I can have a look,
except:
how would we be sure that the preferred shell of the user is that one?

For sure, such behaviors would be a great, in case of failures.
