Proposed fix

This patch inserts a missing quotation at the end of a line
if required (after an appropiate error message is generated).

gcc/m2/ChangeLog:

        * m2.flex: Call AddTokCharStar with a stringtok if
        end of line is reached without a closing quote.

gcc/testsuite/ChangeLog:

        * gm2/pim/fail/missingquote.mod: New test.
