On FreeBSD 5.2.1, I see this compilation error:
In file included from /usr/include/sys/user.h:46,
from ../../gllib/vma-iter.c:63:
/usr/include/sys/ucred.h:75: error: `NGROUPS' undeclared here (not in a
function)

gmake[4]: *** [vma-iter.o] Error 1
Apparently <sys/param.h> is a prerequisite of <sys/user.h> on this old platform.
This patch therefore fixes it.
