[antlr-interest] Synchronizing error messages from filter

I am using a custom filter rule when the lexer finds an unexpected
item. This rule simply skips ahead to the next statement and
outputs a warning message to the user.
There is a problem if a parser rule has caused the lexer to look
ahead several tokens. In this case, the warning message will appear
out of order to the user because it will show up as soon as the
lexer encounters it, before the parser has generated its output from
correct tokens immediately preceding the unexpected item.
Is there any standard way to queue up this message?
