/*** NewSeg - new segment definition
*
* Purpose:
* Create new segment definition based on the module definition
* file segment description. Check for duplicate definitions and
* overlay index inconsistency between attached COMDATs (if any)
* and segment itself.
*
* Input:
* sbName - segment name
* sbClass - segment class
* iOvl - segment overlay index
* flags - segment attributes
*
* Output:
* No explicit value is returned. The segment descriptor in
* symbol table is created or updated.
*
* Exceptions:
* Multiple segment definitions - warning and continue
* Change in overlay index - warning and continue
*
* Notes:
* None.
