[PATCH 2/3] cobol: Use sym_name_t constructor to instantiate new object

[Pietro Monteiro]

GCC 5.4 can't build a sym_name_t from a const char * because
sym_name_t constructor is marked explicit.  Use the constructor then.

gcc/cobol/ChangeLog:

        * symfind.cc (reduce_ancestry::reduce): Use sym_name_t
        constructor when initializing symbol_map_t::value_type none.
