'anu' as a relative clause marker

[aclynes at ubd.edu.bn]

Older speakers of Brunei Malay appear to use /anu/ as a relative clause
marker.  (Another 'anu' functions as a hesitation marker in BM, as in other
dialects of Malay).  Blust 1974 reports a form /anuq/ 'which' in the
related language Murik.
Is a cognate form found elsewhere?  Thanks for any pointers.
