Re: Reporting warnings from pdftex itself (not LaTeX macro layer)

[Andreas Matthias]

Here are the functions that generate the warnings.

pdfTeX:

<https://github.com/TeX-Live/texlive-source/blob/trunk/texk/web2c/pdftexdir/pdftex.web#L15627-L15643>

luaTeX:

<https://github.com/TeX-Live/texlive-source/blob/trunk/texk/web2c/luatexdir/tex/errors.c#L988-L1040>

Ah sorry, you are right. It seems that AUCTeX has to parse the log
output to detect additional form in to deal with this issue :-(

Are you sure that the additional warning is of the form
pdfTeX warning (ext4): FOO BAR BLAH BLAH...
? Or is there possibility that there are yet more other forms to consider?
