Usage: fixeabidefs.bat [-analyse|-list|-update] build_log.log 

Parses the output from build_log.log and locates all MAKEDEF errors where ARMV5 built

object files do not include exports specified in the current, frozen, EABI .def file.

Where this has occurred, the tool checks against an internal list to determine

whether these are redundant exports that are no longer required.

-analyse  Process MAKEDEF errors and warnings list .def files that cannot be updated by this tool.

-list     Lists all .def files that will be updated by the tool.

-update   Creates updated .def files with redundant exports removed.

Updated .def files have redundant exports removed by "back-filling" from unfrozen exports

flagged against the same .def file.  If no unfrozen exports are available, the "ABSENT"

export placeholder is used to effectively remove the export, but maintain a degree of BC.

NOTE: The tool assumes that the original build source layout is replicated on the drive

where it is being executed.

Redundant exports processed on the following regex:
