I don't know yet. I've been trying to lay out a prerequisite task (check to
make sure that no GNU awkisms will cause improper behavior) before we change
a major program that has been "standard" to NetBSD for YEARS. Basesrc and
pkgsrc aren't the only places where awk scripts exist; awk is a widely-used
favorite of sysadmin for producing local system management scripts. So
cleansing basesrc and pkgsrc is not sufficient to ensure that we won't break
The task is pretty simple: read gawk.info and find the GNUisms, and check
that they either work in nawk, or cause a nawk abort. This is, put simply,
a REGRESSION TEST--something we have resolved to do more often wherever
possible--so your destructive attempts to prevent this should be ignored.

Yup, and that mistake means that the above is now a required prerequisite
step for going back to nawk in /usr/bin/awk. How /usr/bin/awk works For
You, installed on Your System, has zero relevance to the NetBSD user
community as a whole. Please go away and come back when you have gained a
sense of regression testing.
