When emerging gdbm-1.8.3-r3 on my system, off_t is 4 bytes. Therefore the gdbm files are of about 2 GB maximum size. Trying to create databases with greater sizes results in gdbm fatal: write error If gdbm is built with off_t defined as 8 bytes, much larger gdbm files can be created. However previous database files created with off_t of 4 bytes cannot be modified or read. I am wondering whether gdbm could be built with this flexibility.
