Can you please share a full example of the problem you're trying to
solve, as well as the platform and gawk version?

On my system, I do not see any such issue:

bash-4.2$ ./gawk -v r0=1,234,567 'BEGIN 
{r0=gensub(/([0-9])[,]([0-9])/,"\\1\\2","g",r0); print r0}'
1234567
bash-4.2$ ./gawk --lint -v r0=1,234,567 'BEGIN 
{r0=gensub(/([0-9])[,]([0-9])/,"\\1\\2","g",r0); print r0}'
gawk: cmd. line:1: warning: `gensub' is a gawk extension
1234567

This is using gawk from the master branch.
