It's been in place since Firebird 1.0 on Windows. And, with Linux, it
depends if the kernel supports 64-bit file I/O.

Under FAT-32, the limit is 4GB. Under Linux 32-bit file I/O, it's
2GB.

With NTFS, it's not a problem. Your more likely to hit the volume
limit than the max file size limit.

And, at the present time, there's a per table size limit that was
reported(some say 40GB and some say 80GB), but that limit will be
removed in Firebird 2.0.
