ScannerG.unexpToken

Outputs a message through the scanner's msg_handler, resulting from an unexpected token in the input stream. Note that you should not call g_scanner_peek_next_token() followed by g_scanner_unexp_token() without an intermediate call to g_scanner_get_next_token(), as g_scanner_unexp_token() evaluates the scanner's current token (not the peeked token) to construct part of the message.

symbolName string: the name of the symbol, if the scanner's current token is a symbol.
message string: a message string to output at the end of the warning/error, or NULL.
