Author: jilles Date: Sun Jan 30 20:37:42 2011 New Revision: 218102 URL: http://svn.freebsd.org/changeset/base/218102 Log: MFC r217704: getgroups(2): Remove <sys/types.h> and refer to sysconf(3). Because {NGROUPS_MAX} may become variable, its value should be obtained using sysconf(3). In head, r217704 removed mention of <sys/param.h>; this was not mentioned in stable/8.
