Code cleanup
Description:
I had moved an fclose() in my earlier fix and it could lead to a resource
leak in certain error conditions.
Also, prepared file for Albert to expand to test with files larger than
2GB... :-)
Solution:
Moved fclose() call back to original position.
Put in type cast for FAMILY_SIZE macro.
Platforms tested:
FreeBSD 4.4 (hawkwind)
