-Dsegsize only accepts integers here and it's expressed in GB, so only
1 will actually work.  Presumably you could set a size up to 2GB - 1
block using -Dsegsize_blocks instead and it would work, but that's
clearly documented as developer-only.  I noticed that too and
scratched my head for a moment, but I think Michael used a defensible
cut-off and a defensible error message, they just disagree :-)
