a bit of testing shows that at least FreeBSD 4.10 behaves similiar to
OpenBSD/i386 and I found the following discussion too:

http://docs.freebsd.org/cgi/getmsg.cgi?fetch=3759+0+archive/2003/freebsd-standards/20030511.freebsd-standards


that hints that setting ERANGE on an underflow (vs an overflow) is
implementation specific though I ws unable to verify that this is indeed
the case ...
