(do_define): Keep info on source file of a symbol. * coffgrok.h (coff_symbol): New field. * srconv.c (PROGRAM_VERSION): Now 1.3 (wr_rl): Use external ref number for symbol. (wr_dus): Only keep one source file per debug unit. (wr_dln): Always emit line numbers for first source file, (wr_globals): Emit globals in the du of their owning source file.
