af5e6e182d * the TOmfLibDictionaryEntry class in unit owomflib converted to two identical 
nested classes inside TOmfLibObjectWriter and TOmfLibObjectReader. The reason
  is I'm planning to change the class, used in TOmfLibObjectWriter, but not the
  one in TOmfLibObjectReader. And using nested classes keeps things clean and
  avoids exposing implementation details in the interface of the owomflib unit.
* also changed 'private' to 'strict private' in the classes of the owomflib to
  reduce the risk of interference between TOmfLibObjectWriter and TOmfLibObjectReader.

  be easily demonstrated by the fact that running 'make regdat' in the compiler

information in OMF LINNUM records, in addition to the DWARF debug information.
  This enables source level debugging on i8086-msdos, when using the Open Watcom
  Debugger, provided the source was compiled with this option and the external

  does not yet support generating debug information).

  honoured by FPC on the callee side.

23250a2ead + allow declaring near and far procvars in all i8086 memory models. Only simple 
procvars can be declared near or far. Methodpointers/nested proc vars, etc
  must still follow the default calling model of the current memory model. Note
  that this feature isn't TP7 compatible (TP7 doesn't allow near procvars at
  all), but is common to 16-bit C compilers and is quite useful for calling
  external code (e.g. for far calling BIOS or some other real mode API entry
  points from any memory model, etc.)
