/* New stab from Solaris 2.  This uses an n_type of 0, which in a.out files
   overlaps the N_UNDF used for ordinary symbols.  In ELF files, the
   debug information is in a different file section, so there is no conflict.
   This symbol's n_value gives the size of the string section associated
   with this file.  The symbol's n_strx (relative to the just-updated
   string section start address) gives the name of the source file,
   e.g. "foo.c", without any path information.  The symbol's n_desc gives
   the count of upcoming symbols associated with this file (not including
   this one).  */
