And the standard ones can stay as is?
If so, here is the updated patch.
RLIMIT_RSS, RLIMIT_OFILE, RLIMIT_LOCKS, RLIMIT_SIGPENDING, RLIMIT_MSGQUEUE
and RUSAGE_BOTH don't seem to appear in the standard and neither does
RLIMIT_NLIMITS nor RLIM_NLIMITS, so I have prefixed them all with __.

2004-08-12  Jakub Jelinek  <jakub@redhat.com>

        * sysdeps/unix/sysv/linux/bits/resource.h (RLIMIT_SIGPENDING,
        RLIMIT_MSGQUEUE): Add.
	(RLIMIT_RSS, RLIMIT_OFILE, RLIMIT_LOCKS, RUSAGE_BOTH): Prefix
	the enum value with __, adjust define.
        (RLIMIT_NLIMITS, RLIM_NLIMITS): Likewise, adjust for the added
	two limits.
        * sysdeps/unix/sysv/linux/alpha/bits/resource.h (RLIMIT_SIGPENDING,
        RLIMIT_MSGQUEUE): Add.
	(RLIMIT_RSS, RLIMIT_OFILE, RLIMIT_LOCKS, RUSAGE_BOTH): Prefix
	the enum value with __, adjust define.
        (RLIM_NLIMITS): Likewise, adjust for the added two limits.
	(RLIMIT_NLIMITS): Add corresponding enum value, adjust define.
        * sysdeps/unix/sysv/linux/sparc/bits/resource.h (RLIMIT_SIGPENDING,
        RLIMIT_MSGQUEUE): Add.
	(RLIMIT_RSS, RLIMIT_OFILE, RLIMIT_LOCKS, RUSAGE_BOTH): Prefix
	the enum value with __, adjust define.
        (RLIM_NLIMITS): Likewise, adjust for the added two limits.
	(RLIMIT_NLIMITS): Add corresponding enum value, adjust define.
        * sysdeps/unix/sysv/linux/mips/bits/resource.h (RLIMIT_SIGPENDING,
        RLIMIT_MSGQUEUE): Add.
	(RLIMIT_RSS, RLIMIT_OFILE, RLIMIT_LOCKS, RUSAGE_BOTH): Prefix
