Disklabe oddity

I get a strange message from disklabel:
Warning, partition c doesn't start at 0!
Warning, partition c doesn't cover the whole unit!
Warning, An incorrect partition c may cause problems for standard system
utilities

What does this mean?
The disk was formatted by the FreeBSD install procedure.
The system is an older Digital PC (3500) PII 333 Mhz.
The disk is a 40 GB IDE drive (WD)

BTW, I'm looking for a safe way to 'grow' my rootfs, I've looked arround
before, but I'm still not clear on the right procedure for it.
I'm considering reinstalling the system with 5.2, reformatting the disk,
but I don't know if this will clear the error.  It will have a larger
root though.

Thanks for any help/suggestions.
