[fpc-devel] Memory Streams unable to handle reads past 2GB

TCustomMemoryStream
     function Read(var Buffer; Count: LongInt): LongInt; override;

Having Read result declared as LongInt is problematic on 64 bit systems 
with large streams.
Read result MUST be either PtrInt or Int64 but it cannot be LongInt.

Please fix,  Thanks
