#3004 .AREA is issued twice into the asm listing

[Tony Pavlov]

1. declare something like: unsigned char test[20]; in some c-file (mine is src\sdcc4bank2code.c)
2. issue a command:
   sdcc -mgbz80 --no-std-crt0 -I ....\gbdk\include -I ....\gbdk\include\asm -I src\include -c src\sdcc4bank2code.c -bo2 -ba1 -o build\sdcc4bank2code.rel
3. the result is:
   .area _DATA_1
   .area _DATA
   _test::
   .ds 20

".area _DATA" is an artefact; ".area _DATA_1" is a correct area definition.

that happen because of both !areadata and !area are in the dict and there is no check for this in emitRegularMap() of the SDCCglue.c. that might affect not only the GBZ80 target.

i made this kind of fix of emitRegularMap(), but it's a bit dirty:

      else if (!strcmp (map->sname, DATA_NAME))
        {
          struct dbuf_s temp_buf;
          dbuf_init(&temp_buf, 64);
          dbuf_tprintf(&temp_buf, "!areadata", map->sname);
          if (strcmp(dbuf_c_str(&temp_buf), "!areadata") != 0) {
              dbuf_tprintf(&map->oBuf, "\t!areadata\n", map->sname);
          } else {
              if (options.data_seg && strcmp(DATA_NAME, options.data_seg))
                  dbuf_tprintf(&map->oBuf, "\t!area\n", options.data_seg);
          }
          dbuf_destroy(&temp_buf);
        }

what's about this?

This one is fixed long ago
