This needs to be >=. The spec says that if the value is 0xffffffff, there 
should be a zip64 record with the actual size (even if it is 0xffffffff).

Could you please cite the relevant part?

4.4.8 compressed size: (4 bytes)
4.4.9 uncompressed size: (4 bytes)

"If an archive is in ZIP64 format and the value in this field is 
0xFFFFFFFF, the size will be in the corresponding 8 byte ZIP64 
extended information extra field."


Of course, there is no definition of how they define that "an archive 
is in ZIP64 format", but I would say that is whenever it has any ZIP64 
structures.
