It sounds like your headers in /usr/include/sys are inconsistent
with your kernel.  In FreeBSD 4.3, crhold() was a macro; it was
changed to a function sometime before 4.4..  So it seems like
your /usr/include/sys/ucred.h defines crhold as a function, but
your kernel doesn't have it (ie the kernel is too old).
