Genisoimage: `Value too large for defined data type' when creating 4.7Gb iso file

Problem
I want to create a large iso file to burn to DVD. But mkisofs gives me error:
$> mkisofs -V BackupDar -input-charset utf-8 -o audio.1.iso -R audio.1.dar genisoimage: Value too large for defined data type. File audio.1.dar is too large - ignoring
Solution
Compose the iso of several files, each < 4 Gb.
Since I just want to write backup (dar) files, I let dar generate chunks of 1,175,000,000 bytes:
# Size of an archive (one slice). 4.7Gb fits DVD but 4Gb is limit of `mkisofs'. #+ 1,175,000,000 is 4.7/4 and is optimal for double archiving first and last slice. -s 1175000000
Now mkisofs/genisoimage works all right > 4 Gb.
Environment
- Debian 4.0
- genisoimage 1.1.2 (Linux)

So mkisofs is actually genisoimage.
$> genisoimage -o audio.1.iso -udf -allow-limited-size audio.1.dar genisoimage: unrecognized option `-allow-limited-size'
- mkisofs vs files > 2GB
