[Message part 1 (text/plain, inline)]

True, looking at the new regexp in emacs the escape characters are highlighted in red, indicating an error. I can verify Mattias' modification still works for me.

I can't properly verify the bracketed version of the warning since I don't get those with my ModelSim, but if I manually type out a warning with brackets it does get highlighted when using re-builder. With Reto's modification on the other hand the bracket warning is not highlighted.

The new regexp,

"^\\(ERROR\\|WARNING\\|\\*\\* Error\\|\\*\\* Warning\\)[^:]*:\\( *\[[0-9]\]\\| ([^)]+)\\)? \\([^ \t\n]+\\)(\\([0-9]+\\)):"
                                                                  ^^^^^^^^^

isn't quite right: there are single-escaped square brackets, and the original regexp permitted multiple digits, not just one, between square brackets. The part

  "\[[0-9]\]"

should probably be

  "\\[[0-9]+]"

but the author needs to confirm this.
