The file slave/kprop.c does not compile in the presence of the switch
POSIX_FILE_LOCKS
The function lockf is called with incorrect arguments. Here is a context
diff to make it compile correctly, according to the HP-UX 9.0 man page
description of the lockf call.

Note that I have not yet got so far as testing this on my HP 700 series system.
However, I thought I would pass it on before I forget.
Sincerely,

P.S. The HP-UX 'c89' compiler purports to be a true POSIX compiler. However,
I cannot use it on Kerberos V as you requested in the interim documentation
because the ISODE include files blow up with either an ANSI or POSIX compiler.
Since these are included all over the place, it proved to be impossible to
use 'c89'.
