* makedef.cmd - update a DLL export list using a newly created library file

* standard output gets a sorted list with all entrypoints with entrycodes.

* This list, plus a few .def sentences (LIBRARY, DESCRIPTION and EXPORT)

* `_nc_*' symbols are ignored.

|
* returns 1 when the old def_file is corrupted -- that is, export items are
|
|
* not properly formatted.
|
|
*
|
|
* returns 0 if everything went OK.
