      that ra386dir translates global and unit symbols
    + added a first field in tsymtable and
      a nextsym field in tsym

      records and objects in gdb !)

  Revision 1.46  1998/10/16 08:51:54  peter
    + target_os.stackalignment
    + stack can be aligned at 2 or 4 byte boundaries

  Revision 1.45  1998/10/15 16:20:41  peter

  Revision 1.39  1998/10/13 08:19:42  pierre
    + source_os is now set correctly for cross-processor compilers
      (tos contains all target_infos and
       we use CPU86 and CPU68 conditionnals to
       get the source operating system
       this only works if you do not undefine
       the source target  !!)
