Clean up unexcoff.c.

 unexcoff.c (report_error, make_hdr, write_segment)
 (copy_text_and_data, copy_sym, mark_x, adjust_lnnoptrs, unexec):
 Convert argument lists and prototypes to ANSI C.
 (make_hdr, write_segment): Remove unused variables.
 (unexec): Remove commented-out line.  Initialize `new' to shut up
 compiler warnings.
