For testing purposes, I am looking for a comprehensive list of all errors and warnings that TeX, and LaTeX can output. I don't mean errors and warnings produced by all packages, as this would give an ever-changing list, just TeX and LaTeX, which should be stable.
Has anyone ever produced such a list, e.g., for internationalization?

latex.ltxreveals 32 occurrences of\@latex@warningand 84 of\@latex@error: probably a few too many for an answer! – Joseph Wright♦ Jan 26 at 17:19strings `which pdflatex`to get a list of all strings inside thepdflatexbinary. There are the TeX error message included, but the list is 16k of lines, so I don't post it here ;-) – Martin Scharrer♦ Jan 26 at 18:46
