* cmpdef.cmd - compares two .def files, checking whether they have
|
||
|
|
* the same entries with the same export codes.
|
||
|
|
*
|
||
|
|
* returns 0 if there are no conflicts between the files -- that is,
|
||
|
|
* the newer one can replace the older one.
|
||
|
|
*
|
||
|
|
* returns 1 when either of the files is not properly formatted and
|
||
|
|
* when there are conflicts: two symbols having the same export code.
|
||
|
|
*
|
||
|
|
* the standard output shows a list with newly added symbols, plus
|
||
|
|
* replaced symbols and conflicts.
