There are some preliminarily code for this purpose, though
it is not completed yet.

With the patch below, line directives are activated in the
intermediate C code, and gdb will find your COBOL files if
you compile them with option `-g':

       output_line ("cob_source_line = %d;", x->loc.first_line);
     }
 }

Note that this patch does not cover all COBOL lines, and thus
not very useful yet.  For now, it is better to generate C code
with option -C, compile it by using gcc with option -g, and
trace the C code.

I am going to implement better debugging support after writing
some documentation in English.
