RNG1302 compile error on CTL-OPT

Good day, folks,

I ran compile command CRTSQLRPGI on a source member that had the following control statement:

c000   ctl-opt dftactgrp(*yes)
c000    // -- bnddir('AVRTBNDDIR')
c000    datfmt(*iso) timfmt(*iso)
c000    option(*nodebugio:*nounref)
c000    extbinint(*yes)
c000    alwnull(*usrctl);

And got the following compile error:

013105    option(*nodebugio:*nounref)
======>   aaaaaa
*RNF1302 20 a      013105  A keyword is specified more than once; keyword is ignored.

Anybody else get this or figure this out? I did once but memory failed to bring it back...

In case it helps somebody recollect, a colleague at work said he got this before, and the problem is "further down", but he didn't remember more exactly.
