Hi Christian,
As described below, the highlighting performed by :MatchParen gets
confused by the AC_MSG_* syntax region.

":help pi_paren" explains the problem

Since the opening ([ are highlighted as configstring, they aren't
considered a valid match for the closing ]).
Changing the syntax region's name to configmsg, like in the attached
patch, fixes the problem. The contents are still highlighted like a
string, but it doesn't confuse the paren matching.
Cheers,
